Which statement best describes the triangle law of vector addition?
(a) If two vectors are placed head to tail, the third side taken in the same order represents their resultant.
(b) If two vectors are placed tail to tail, the diagonal of the parallelogram formed gives their resultant.
(c) When two vectors are represented by two sides of a triangle taken in order, the third side taken in the opposite order represents their resultant.
(d) The magnitude of the resultant of two vectors equals the arithmetic sum of their magnitudes, regardless of their directions.
