Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sentence requires a conditional conjunction to complete the philosophical thought. 'Unless' correctly establishes that doing something for someone who cannot repay you is the requirement for a 'perfect day'. 'Though' and 'whenever' do not fit the logical structure of the 'even though... unless' contrast.
