The correct answer is

In RAM, which remains powered with a small amount of electricity

In standard Windows Sleep mode, the operating system saves the current session, including open applications and documents, in the RAM (Random Access Memory).

The laptop keeps a small amount of electrical power flowing to the RAM so that its contents are retained, allowing the system to resume almost instantly when woken up.

The BIOS chip only stores firmware settings, the system drive is used in Hibernate mode instead of Sleep mode, and the CPU cache is too small and volatile to hold an entire session.

Hence, in Sleep mode, the current session is primarily stored in RAM, which remains powered with a small amount of electricity.
