Question

which two points are not at 0 degrees either north or east? b c a d

Explanation:

Step1: Check point A

Point A is at $45^{\circ}N$ latitude and $0^{\circ}$ longitude. Its longitude is 0 degrees (prime - meridian), but we are checking for non - 0 degrees in north or east. Its latitude is non - zero in the north direction.

Step2: Check point B

Point B is at $0^{\circ}$ latitude (equator) and some non - zero east longitude. But we are looking for non - 0 in north or east for both coordinates. Since latitude is 0, it doesn't meet the criteria.

Step3: Check point C

Point C has a non - zero south latitude ($30^{\circ}S$) and a non - zero west longitude ($120^{\circ}W$). It is not at 0 degrees either north or east.

Step4: Check point D

Point D has a non - zero south latitude ($45^{\circ}S$) and a non - zero east longitude ($100^{\circ}E$). It is not at 0 degrees either north or east.

Answer:

C. C, D
