Correct Answer : d ) \(5\sqrt{5}\) km and North- West facing

Explanation :

Depicting the given information in the figure we get,

In the triangle HAO

Using Pythagoras theorem,

HO2 = HA2 + OA2

HO =\( \sqrt{100+25}\)

HO =\(5\sqrt{5} \) km

Thus, shortest distance between Home and office is \(5\sqrt{5} \) km and the office North-West facing.

Hence, (d) is the correct answer.
