Solution
The correct option is BB
Answer B: Boron
Boron is extremely immobile in plants and is not
translocated to new growth, but moves readily in soil. Deficiencies often occur
when pH is between 6.0 and 7.5, on deep sandy soils, and when high rates of N,
K, and Ca are used. Deficiency more apparent during drought stress.
