Match the column \begin{tabular}{l|l} Column - I & Column - II \end{tabular} (a) Body line on a (p) is a self adjusting horizontal surface \(\quad\) force (b) Static friction (q) is a maximum value of static friction (c) Limiting friction (r) is then limiting friction (d) Dynamic friction (s) force of friction \(=0\) (A) $\mathrm{a}-\mathrm{s}, \mathrm{b}-\mathrm{p}, \mathrm{c}-\mathrm{q}, \mathrm{d}-\mathrm{r}$ (B) $\mathrm{a}-\mathrm{p}, \mathrm{b}-\mathrm{q}, \mathrm{c}-\mathrm{r}, \mathrm{d}-\mathrm{s}$ (C) $\mathrm{a}-\mathrm{s}, \mathrm{b}-\mathrm{r}, \mathrm{c}-\mathrm{q}, \mathrm{d}-\mathrm{p}$ (D) $\mathrm{a}-\mathrm{r}, \mathrm{b}-\mathrm{q}, \mathrm{c}-\mathrm{p}, \mathrm{d}-\mathrm{s}$

In order to match the terms correctly, we first need to know what each term in Column I means: (a) Body line on a: This term seems incomplete, so we will come back to this once we analyze other terms. (b) Static friction: This is the force that resists the motion of two objects in contact and at rest relative to each other. (c) Limiting friction: The maximum value of static friction that can act between two objects before they start to move relative to each other. (d) Dynamic friction: Also known as kinetic friction, it is the force that resists the relative motion of two objects that are in contact and already in motion. #Step 2: Analyze the terms in Column II#

Now we need to understand what each term in Column II means: (p) Is a self-adjusting horizontal surface force: This could refer to static friction as it adjusts itself to prevent the relative motion between two objects until its maximum value is reached. (q) Is a maximum value of static friction: This clearly refers to the limiting friction. (r) Is then limiting friction: This is a direct reference to limiting friction. (s) Force of friction = 0: This may refer to the condition where there is no frictional force acting on a body. Now going back to term (a), it seems that it might be an error or typo. Since there are no other instructions, we will continue to match the terms with the given options. #Step 3: Match the terms from Column I to Column II#

Based on the understanding of each term, we can now match them as follows: (a) Body line on a: Match with (s) because it is the only remaining term. (b) Static friction: Match with (p) because it is a self-adjusting horizontal surface force. (c) Limiting friction: Match with (q) because it is the maximum value of static friction. (d) Dynamic friction: Match with (r) because it is direct reference to limiting friction. #Step 4: Find the corresponding answer choice#

The corresponding matching pairs are: \(a - s, b - p, c - q, d - r\) These matches correspond to option (A). Therefore, the correct answer is: (A) \(a - s, b - p, c -q, d - r\)
