REPLACE('GEORGE' 'GE' NULL);
C
Correct answer
Explanation
REPLACE('GEORGE', 'GE', NULL) removes occurrences of 'GE' from 'GEORGE'. When the replacement string is NULL, Oracle's REPLACE removes the matched pattern entirely. Removing 'GE' from 'GEORGE' leaves 'OR'. The question syntax is missing commas but this is the intended logic.
