They Should Have Put It In A Smaller Jar

This week's "Smithsonian Snapshot" is a giant squid eye from their collection, not currently on display at the museum, i.e. ONLY AVAILABLE ONLINE:

But they TOTALLY should have put it in a smaller jar, 'cause, like, it just doesn't look that big.

Background cephalopod trivia time! Can you identify:

A) the brown&white striped object visible behind the eye through the jar?
B) the objects in the jar at the far right of the photograph?
C) the squid in the jar peeking out from behind the eye jar?
