Why the answer is B, and why the others tempt you.
Thinning is the practice of removing excess seedlings from a stand to achieve the optimum plant population per unit area. This ensures that the remaining plants have adequate space, light, water, and nutrients for vigorous growth. It is commonly practised when seeds are sown in clusters or when germination rate exceeds the desired population.
