Dustin, Aged 17, Purchased a Car from Speed Auto Sales

Dustin, aged 17, purchased a car from Speed Auto Sales for $1,000. The following year, his father gifted him a brand new car on Dustin's 18th birthday. Dustin returned the car to Speed Auto Sales the next day, and demanded his money back. At the time of disaffirmance, Dustin was 18, the age at which he was considered an adult in his jurisdiction. Will this disaffirmance be enforceable in the court of law?

A) No, since Dustin did not give Speed a signed revocation.
B) Yes, since Dustin disaffirmed during the year he reached his adulthood.
C) No, since the disaffirmance must be written when the price exceeds $500.
D) Yes, since the courts and laws always rule in the favor of minors.
E) No, since Dustin has reached adulthood and disaffirmance can be expressed only by a minor.
