Solution:

Concept- The basic concepts of the polygon law of vector addition can be used to solve the aforementioned issue. The law's concepts and essential principles are utilised to identify the polygon and to analyse the proper values of the vector angles.
The vectors' total equals A+B+C=0.
The polygon rule states that only when a polygon is created as a closed polygon or a triangle, the sum of the three vectors equals zero. The two vectors have the same magnitude under the provided conditions, while the third vector has a magnitude that is   times greater than either of the two identical vectors. The resulting triangle is thus referred to as a right-angled triangle.
Then, the values of angles are given as,
Angle between the and is, .
Angle between the and is, .
Angle between the and is, .
Therefore, the angles between the vectors are .
Hence, option 4 is correct.
