The correct option is C Assertion is correct but Reason is incorrect.
Sulfur deficiency is characterized by the uniform pale green chlorosis throughout the plant. Veins do not retain a green colour, and in many cases, they may be even paler than the interveinal tissue.
Nitrogen is the important constituent of proteins, nucleic acids, chlorophyll, ATP etc. The bulk of nitrogen in nature is fixed by symbiotic bacteria, Rhizobium. Hence option C is correct.
