The Scientists were able to use ice to study ancient climates through the glacial deposits and ice cores.

Scientist studies previous and ancient climatic condition to understand what to expect in the nearest future.

Glacial deposits and ice cores are the two sources that are useful to study of ancient climates because information are preserved and locked in time through them.

Hence, the Scientists were able to use ice to study ancient climates through the glacial deposits and ice cores.

Therefore, the Option A is correct.
