Simply look up the numbers in the pictures.

+5, - 8 , + 2 1/2, - 6 1/4, - 3/4

Since we are not interested if it is East or West we ignore the + or - sign.

We only add up the sizes.

So we take the modulus of each number and add to the modulus of the next.

So the answer is:

|5 | + |-8 | + | 2 1/2| + |-6 1/4| + |-3/4|

Option C is the best answer. Though it ignored the minus sign.
