If the angle of elevation of an object is $0^\circ$ , the object lies on the—

azenith
bsame horizontal level as the observer
cdirectly above the observer
ddirectly below the observer

ব্যাখ্যা

A $0^\circ$ angle of elevation means the line of sight coincides with the horizontal, so the object is at the observer's own eye/horizontal level.
