Q6: The carry propagation delay in full-adder circuits:

A decreases in a direct ratio to the total number of FA stages.

B increases in a direct ratio to the total number of FA stages but is not a factor in limiting the speed of arithmetic operations.

C is normally not a consideration because the delays are usually in the nanosecond range.

D is cumulative for each stage and limits the speed at which arithmetic operations are performed.
