For two vectors \( \mathbf{A} \) and \( \mathbf{B} \) which lie in a plane. Which of the following statement is correct?
(a) If magnitude of \( \mathbf{A} \) and \( \mathbf{B} \) vector is 3 and 4 and they add upto give vector having magnitude of 5 , then they must be perpendicular vector.
(b) If they add up to give more than 5 , then they must be inclined at obtuse angle.
(c) If they add upto give less than 5 , then they must be inclined at acute angle.
(d) None of the above
