184. The carry propagation delay in full-adder circuits:
(a) is normally not a consideration because the delays are usually in the nanosecond range.
(b) decreases in a direct ratio to the total number of FA stages.
(c) is cumulative for each stage and limits the speed at which arithmetic operations are performed.
(d) increases in a direct ratio to the total number of FA stages but is not a factor in limiting the speed of arithmetic operations.
