If a + b + c = 0 , then which of the following is/are correct? 1. a , b , c are coplanar. 2. a b = b c = c a Select the correct answer using the code given below.

Options

  1. A1 only
  2. B2 only
  3. CBoth 1 and 2
  4. DNeither 1 nor 2

Correct answer

C. Both 1 and 2

Step-by-step solution

According to statements (1) and (2), when a + b + c = 0 , then both statements are correct. If a b = b c = c a =0 , then a , b and c are collinear. Therefore, option (C) is correct.
