Option: A is the correct answer.

A) Eastings.

Step-by-step explanation:

In a map the grid is divided into the x-axis and y-axis of which the x-value is given on the east of the origin and the y-value is defined to the north of the origin.

When reading a grid reference number corresponding to a grid on a map, you read eastings the number first.

( since we are read a number as :

(x,y) where y is the value corresponding to the given x-value .

Hence, we read the x-value first which is defined on the east of a grid)
