Assertion (A) $$K_p$$ can be equal to or less than or even greater than the value of $$K_C$$.

Reason (R) $$K_p=K_C(R T)^{\Delta n}$$

Relation between $$K_p$$ and $$K_C$$ depends on the change in the number of moles of gaseous reactants and products.

A
Both (A) and (R) are true and (R) is the correct explanation of (A).
B
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
C
(A) is true and (R) is false.
