The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept:
Electron affinity depends on electronic configuration.
Step 2: Detailed Explanation:
Beryllium (Be) has a stable electronic configuration ($1s^2 2s^2$) and does not readily accept an electron. Similarly, neon (Ne) has a completely filled shell and low electron affinity.
Step 3: Final Answer:
The electron affinity of Be is similar to that of Ne.
