Answer 1

D) 1000

Explanation:

The options of the question are

A) -1000 B) -7 C) 7 D) 1000

we know that

The sea level is the reference value to represent elevation, and it is considered as zero level.

Above sea level is considered positive and below the sea level is considered negative

we have

New Orleans is 7 feet below sea level

so

New Orleans elevation is -7 ft

Oklahoma is 1000 feet above the sea level

so

Oklahoma elevation is +1000 ft

therefore

Oklahoma City's elevation is represented by 1000
