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

The carry propagation delay in full-adder circuits is cumulative for each stage, which directly affects and limits the speed at which arithmetic operations can be performed. This is because each stage must wait for the carry from the previous stage before it can complete its operation.
