You would want to try Shoulder Taps to help you build muscle for your trapezius.
To make sure you are prepared for every outcome so if in the future if something goes unplanned you already somewhat expected it
D. Regular Exercise has been shown to reduce the physical effects of stress.
A wouldn't be correct because at home, you can find plenty of time to relax.
B would be wrong because it is opinion based and would be extremely difficult, if not impossible to experiment for.
And C would be wrong because mental discipline doesn't necessarily means you can take away stress.
Hope this helps!
