Answer 1

Correct answer is (a) special characters beginning with a \ (backslash)

Explanation: An escape sequence is generally a two character string which begins with a \. The role of escape sequences is that they change the state of computer or the peripheral devices attached to it, For example, \n is an escape sequence which implies a new line character.
