Office worker: I have two equally important projects that remain undone. The first one is late already, and if I devote time to finishing it$,$ then I won't have time to finish the second one before its deadline. Admittedly, there's no guarantee that I can finish the second project on time even if I devote all of my time to it$,$ but I should nonetheless devote all of my time to the second one.

$18.$ Which one of the following principles, if valid, most helps to justify the office worker's reasoning?

A It is better to focus one's time on a single project than to split one's time between two projects.

B It is better to finish one of two projects than to risk failing to finish both projects.

It is better to first finish those projects that must be

c done than to interrupt them with projects that are merely optional.

It is better not to worry about having failed to finish a

D project on tinfe than to allow such worry to interfere with finishing a competing project on time.

It is better to attempt to finish a project on time than to E attempt to finish a late project that does not have higher priority.
