S1. The early bird gets the worm. S2. To go about one's tasks expeditiously is to achieve one's goals. The second statement:

The first statement is a well-known proverb meaning that those who act early/promptly succeed. The second statement essentially restates the same idea in non-metaphorical language: acting expeditiously (promptly/efficiently) leads to achieving one's goals. The second statement reinforces the assumption underlying the proverb. Note: the proverb itself is metaphorical, and the second is the literal/explanatory version — so the second does NOT provide a metaphorical reassertion (the metaphor is in the first). It reinforces the assumption of the first. Hence (c) reinforces the assumption of the first is correct.
