Which is the angle of elevation from c to b?

Angle of elevation from C to B will be ∠4. Option (1) will be the answer.

Angle of elevation of an object from a point on the ground is defined by,

   "Angle between the horizontal line and line of site (line joining the observer and the object above the horizontal line)"

Following the definition,
