Seller and Buyer Negotiate for the Sale of 100 Acres

Seller and Buyer negotiate for the sale of 100 acres of land.They orally agree on a price of $100,000,with payment to be made within 10 days and the deed delivered within another 30 days.Buyer sends Seller a letter in which all these terms are included,along with a check for $100,000 that Seller deposits.Seller fails to deliver a deed,and Buyer seeks to enforce the contract.This contract is:

A) enforceable,because Buyer had partly performed the contract by making payment
B) unenforceable,because there is no writing signed by Seller
C) enforceable,because Buyer sent a memorandum sufficient against himself,which binds Seller unless Seller objects,which he did not
D) unenforceable,because the parol evidence rule applies
