Consider the following statements A and B given below and identify the correct answer.A) Vectors i^+3j^+5k^ and 2i^+6j^+10k^ are parallelB) i^+j^+k^ represents a unit vector

If the vectors and are parallel then . In statement (A) , So Statement (A)is trueMagnitude of unit vector is 1 .But in statement (B) , magnitude of the vector is = √3 .So statement-(B) is falseTherefore option - (2) is right.
