Answer: Option A

Each beetroot fruit contains 2 - 6 seeds, hence requiring Thinning. As they get crowded in the row. Young tops make excellent greens. After thinning, the plants should be 2 to 3 inches apart.
Thinning of beets can be done in two ways. Either pull the extra seedlings out completely or just cut off the leaves. The latter is the preferred method because it results in less root disturbance to the seedlings you keep, but I usually just pull the extras out.
