Answer: Seed drill is used to sow seeds.

Step by step solution

Consider statement (1)

Seed drill is used to sow seeds. This statement is correct. A seed drill is a machine that sows seeds in the soil at specific intervals and depths, allowing for efficient planting and even, controlled germination. So, option (1) is correct.

Consider statement (2)

Four or five ploughs are attached to the plank of the seed drill to sow the seeds deeper. This statement is incorrect. A seed drill typically contains a seed hopper, metering device, and furrow openers or coulters that create furrows and place seeds at the appropriate depth. Ploughs are not attached to the seed drill to sow the seeds deeper; instead, the depth is controlled by the coulters or furrow openers. So, option (2) is incorrect.

Consider statement (3)

Speed drill is also used to put manure near the roots of the small plants. This statement appears to contain a typographical error – it should be "seed drill" instead of "speed drill." With that correction, the statement is still incorrect. A seed drill is primarily designed for sowing seeds, not for applying manure near the roots of small plants. Fertilizer application could be done with other equipment or modifications but is not a primary function of a typical seed drill. Hence, option (3) is incorrect.

Final conclusion

Based on our analysis, the correct alternative among the given statements is statement (1), meaning "Seed drill is used to sow seeds."
