$50-$Mary, $16,$ an athlete, signs a long$-$term endorsement deal with a well$-$known brand and is compensated for several years. At age $20,$ she decided she wanted to take a better endorsement deal, so she tried to void the agreement because it was made when she was a minor and lacked capacity. Mary will not likely succeed in having her agreement voided, as she has passed the period of incapacity. Find which category does this example belong to$?$

a$-$Mental Incapacity:

b$-$Minors Have No Capacity to Contract

c$-$Legality

d$-$Breach of Contract and Remedies
