JEE Main 2023 Mathematics question on Matrices and Determinants

Consider the following system of equations
ax+2y+z=1ax + 2y + z = 1
2ax+3y+z=12ax + 3y + z = 1
3x+ay+2z=β3x + ay + 2z = \beta
for some α,β∈R\alpha, \beta \in \mathbb{R}. Then which of the following is NOT correct.
  1. A.
    It has no solution if α=−1\alpha = -1 and β≠2\beta \neq 2
  2. B.
    It has a solution for all α≠−1\alpha \neq -1 and β=2\beta = 2
  3. C.
    It has no solution for α=−1\alpha = -1 and for all β∈R\beta \in \mathbb{R}
  4. D.
    It has no solution for α=3\alpha = 3 and for all β≠2\beta \neq 2
