D Correct answer
Explanation

Negative feedback in amplifiers provides multiple benefits: improved thermal stability (reducing drift with temperature), better noise reduction, and reduction in gain (which is actually a trade-off for the other benefits). All three outcomes are consequences of applying negative feedback, making option D the correct comprehensive answer.
