The key to answering this question is to find the pair that are both depositional features and are associated with continental glaciation.

In the case of A, eskers are depositional and continental glaciation features but aretes are erosional and alpine glaciation features.

In the case of B, cirques are erosional and alpine glaciation features while kettles are erosional and continental glaciation features.

In the case of C, striations are erosional features for both continental and alpine glaciation while erratics are depositional features for both continental and alpine glaciation.

Therefore, the answer is D. Both are depositional features and both are associated with continental glaciation. Moraines can also apply to alpine glaciation.
