Removal of apical bud results in

The correct option is "more lateral branches".

Understanding Apical Dominance:
In plants, the growing tip of the main stem contains the apical bud (or terminal bud). This bud produces a class of plant hormones called auxins. Auxins flow downwards through the plant stem and actively inhibit the growth of axillary (lateral) buds situated in the nodes below. This biological phenomenon is known as apical dominance, which encourages the plant to grow vertically rather than bushy.

Effect of Removing the Apical Bud:
When the apical bud is removed (a process often referred to as decapitation or pruning):
1. The primary source of auxin is eliminated.
2. Consequently, the concentration of auxin in the lower parts of the stem drops significantly.
3. Without high levels of auxin to suppress them, the lateral (axillary) buds are released from inhibition and begin to grow rapidly.
4. This results in the development of more lateral branches, giving the plant a bushier appearance.
