Mr. A sold Mr. B an option for $500 for a 60-day period starting March 13. In the event the option was exercised, the buyer would be required to complete a 30-day escrow commencing on the day the option was exercised, paying all cash for the property. Mr. B assigned his option to Mr. C for $1,000 consideration. On April 30, Mr. C informed Mr. A that he would pay cash for the property on May 7. Mr. A claimed that the option was void. The option was:
a. void, becae the original buyer sold it without permission.
b. void, becae the proposed purchase date would not be within the 60-day option period.
c. void, even though original holder had sold the option—however, the purchase day was beyond the required date of sale.
d. valid, and the Assignee (Mr. C) would be able to purchase the subject property on May 7.
