The Correct Option is D
Solution and Explanation
Concept:
A notch filter is designed to strongly attenuate a narrow range of frequencies while allowing others to pass.
Step 1: Understand the requirement.
The question asks for reduction of gain at a specific frequency. This requires selective attenuation.
Step 2: Identify the filter.
A notch filter creates a deep attenuation at one frequency. \[ \boxed{\text{Notch Filter}} \]
Step 3: Final Answer.
\[ \boxed{\text{Correct Option (D)}} \]
