C: Dear Mr. Patel

Explanation:

 The best way to write a salutation in a cover letter is using the greeting "Dear" (captalized), and the title followed by the person's family name , which, in this case is already known.  After the name, a comma or a semicolon  should be used. The first contact with the company via Resume was more formal, so now, with the cover letter , it is fine to use "Dear" ,  but "To Whom it May Concern"  is to be avoided.
