Statement $(A)$: The points $(2, 1)$ and $(-3, 5)$ lie on opposite sides of the line $3x - 2y + 1 = 0$.
Reason $(R)$: The algebraic perpendicular distances from the given points to the line have opposite signs.

  $A$ and $R$ are both independently true and $R$ is the correct explanation for $A$.
• B
  $A$ and $R$ are both independently true and $R$ is not the correct explanation for $A$.
• C
  $A$ is true but $R$ is false.
• D
