Solution
The correct option is D Mo
Molybdenum is an important essential micronutrient. Its deficiency leads to mottled chlorosis with marginal infolding and necrosis, whiptail in crucifers, upper leaf half wither in monocots, loosening of cauliflower head, growth retardation, etc.
Brassica is a genus of plants in the mustard family (Brassicaceae). The members of the genus are informally known as cruciferous vegetables, cabbages, or mustard plants. So, deficiency of Mo leads to whiptail in them.
