Answer: Option A

Solution(By Examveda Team)

The cation exchange capacity is a measure of how many cations can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positively charged atoms or molecules (cations) but allow these to exchange with other positively charged particles in the surrounding soil water.
CEC values for organic soils lie in the range of 50 - 100 meq/100 g.
