Why are seeds used in farming?

Correct answer: To grow crops

The direct answer is A: seeds are used in farming to grow crops. A seed contains the beginning of a new plant. When a healthy seed receives suitable moisture, air, warmth, and care, it germinates. First, the seed absorbs water; then the embryo begins to grow; a root develops downward, a shoot grows upward, leaves appear, and the plant continues growing into a crop. Farmers select, sow, and care for seeds so that food, fibre, oil, or other agricultural products can be produced. Good-quality seeds generally support healthy and more uniform crop growth, though successful farming also needs proper soil, water, nutrients, and protection. Option A is correct because crop production begins with sowing suitable seeds. Option B is wrong because seeds are not normally used to decorate a house; decorative objects may be made from other materials, but that is not their farming purpose. Option C is wrong because stitching clothes requires cloth, thread, and sewing tools, not seeds. Option D is wrong because vehicles operate with fuel or other power systems, not seeds. The essential exam chain is “seed → germination → plant → crop.” Memory cue: seeds are the starting point of crop growth.
