E Correct answer
Explanation

getchar() reads one character from stdin and returns it as an int (or EOF). Correct usage: c = getchar(). Option A uses getc() without stream argument. Options B and D pass address to getchar (wrong - it takes no arguments). Option C passes stdin to getchar (wrong signature). Only option E is correct.
