Which statement best describes an icebox rivet?

Explanation:
Icebox rivets are age-hardenable aluminum rivets kept in a sub-freezing ice box to slow down their hardening. The cooling slows the aging process of alloys like 2017 or 2024, so the rivet remains ductile and easy to form when it's time to install them. If they weren’t kept cold, they would harden too quickly and be difficult to drive properly, risking a poor joint. So storing them in an ice box to delay hardening is the defining feature. The other statements don’t capture this practice or the materials involved.
