The correct option is D You can stand up and make changes. You can sit and complain.
A compound sentence is made up of two independent clauses, which are
complete sentences on their own. Alternative compound sentences express a choice between two alternatives. Option D expresses two alternatives, "make changes" and "complain", hence option D is correct. Option A expresses a cause and effect relationship between the sentences, hence it's not the appropriate option. Option B expresses two contrasting ideas, "met with...accident" and "went to work", hence it isn't the appropriate option. Option C is inference based, where one is deduced from the other, hence it's not an appropriate option.
