Once you attempt the question then PrepInsta explanation will be displayed.
clearly, the narrator starts from A, moves
towards north-east a distance of 10 m up to B,
turns left (90 degrees anti-clockwise) and moves
7.5 m up to C. Clearly, C lies to the north of A.
Also , ΔABC is right-angled at B. So,
AC2 = AB2 + BC2 = (10)2 + (7.5)2
= 100 + 56.25 = 156.25
AC = √ (156.25) m = 12.5 m
Thus the narrator is 12.5 m to the north of
his initial position.
Hence, option D is correct.
