If a, b, b are non-coplanar vectors and \[\lambda \], is a real number, then\[[\lambda (a+b){{\lambda }^{2}}\,b\,\,\lambda c]=[ab+cd]\]for     AIEEE  Solved  Paper-2005

A) exactly two values of \[\lambda \]

B) exactly three values of \[\lambda \]

C) no value of\[\lambda \]

D) exactly one value of\[\lambda \]

Correct Answer: C

Solution :

                          So, no real value ofexists. Alternate Solution                                   No real value ofexists.
