The Correct Option is C
Solution and Explanation
In a parallel adder, each full adder adds two corresponding bits of the operands and a carry bit. For a four-bit parallel adder, you need four full adders, one for each bit of the operands.
Thus, the correct answer is \( 4 \).
Thus, the correct answer is \( 4 \).
