The four points whose position vectors are given by $2 \bar{a}+3 \bar{b}-\bar{c}, \bar{a}-2 \bar{b}+3 \bar{c}$, $3 \bar{a}+4 \bar{b}-2 \bar{c}$ and $\bar{a}-6 \bar{b}+6 \bar{c}$ are

• A

  Collinear
• Correct answer
  B

  Coplanar
• C

  Vertices of a square
• D

  Vertices of a rectangle

Hence, the correct answer is option: 'B'.
