Explanation:

1. Analyze each option:

• "Impermissible" means not allowed, but helping beyond the shift is a good act, so this is incorrect.
• "Obligatory" means required, but they weren't required to help the next shift, so this is incorrect.
• "Supererogatory" refers to acts that are morally good but not required, which fits their decision to help beyond their shift.
• "Futil" (likely "Futile") means useless, and their help was not useless, so this is incorrect.

Answer:

C. Supererogatory (assuming the third option is "Supererogatory" as per the context, with the identifier and text: C. Supererogatory)
