Explanation:

Let’s break it down:

- Aman starts at A, goes 10m east to B.

- Turns right (now heading south), walks 8m to C.

- Turns right again (now heading west), walks 6m to D.

- Turns left (now heading south), walks 8m to E.

- Turns left again (now heading east), walks 6m to F.

The question is about the shortest distance between A and C.

- From A to C:

* Horizontal movement: 10m east.

* Vertical movement: 8m south.

- This forms a right triangle, with legs 10m and 8m.

- So, use Pythagoras:

Distance = v(10² + 8²) = v(100 + 64) = v164m

Let’s look at the options:

- v184m (nope)

- 18m (nope)

- v154m (nope)

- v164m ? this one!

- 164m (nope, you need the square root)

Correct Answer: Option 4 – v164m
