C Al and Si
D N and S

Answer 1

The answer to your question is letter b) He and Ne

Step-by-step explanation:

B He and Ne These elements have similar properties becase they are in the same group (8A).

C Al and Si These elements do not have similar properties because Al is in group 3A and Si is in group 4A. This is not the right answer.

D N and S These elements do not have similar properties because N is in group 5A and S is in group 6A. This is not the right answer.
