Cbicycling to build leg strength
Dswimming to improve coordination

Verified Answer :

C. bicycling to build leg strength.  It is the most general activity among the
four choices.  Although it says to build
leg strength it is not so specific for what activity it will be used for.  The other choices were more specific in their
goals.
