Answer: Option D
Solution(By Examveda Team)
Vanadium and Sodium are non-essential but useful nutrients for plants. Plants require 17 essential nutrients for their growth and development, but vanadium and sodium are not on that list. Vanadium is a multivalent redox-sensitive metal, low levels of vanadium elevate plant height, root length, and biomass production due to enhanced chlorophyll biosynthesis, seed germination and also for essential element uptake.Sodium is needed by a few varieties of plants to help concentrate carbon dioxide, but in trace amounts to promote metabolism.
