Correct answer: C

To convert the IEEE-754 32-bit floating point representation to decimal: 1. Sign bit is 0, so the number is positive. 2. Exponent bits are 10000000, which equals 128 in decimal. Subtract the bias of 127 to get the actual exponent: 128 - 127 = 1. 3. Mantissa bits are 110..., representing 2^-1 + 2^-2 = 0.75. The significand is 1 + 0.75 = 1.75. 4. Calculate the value: 1.75 * 2^1 = 3.5.
