A blind person after walking 10 steps in one direction, each of length \( 80 \mathrm{~cm} \), turns randomly
\( \mathrm{P} \) to the left or to the right by \( 90^{\circ} \). After walking a

W total of 40 steps the maximum possible displacement of the person from his starting position could be :-
(1) \( 320 \mathrm{~m} \)
(2) \( 32 \mathrm{~m} \)
(3) \( 16 / \sqrt{2} \mathrm{~m} \)
(4) \( 16 \sqrt{2} \mathrm{~m} \)
