If we use SQL and Callsection at same time then Database deadlock will occur. So we cannot use at sametime. Thatswhy both are mutually exclusive.

It's because the processor can't decide which action to do first. That's why we cannot use at the same time.

if sql n callsection are not mutually exclusive den deadlock will occur so for prevention they are mutually exclusive.
deadlock refers to specific condition when 2 or more process are each waiting for each other to release resource.
