Consider graph of Gibbs free energy  vs extent of reaction with points (a), (b), (c). Number of true statements is:
A. Reaction spontaneous at (a) and (b)
B. Reaction at equilibrium at (b) and non-spontaneous at (c)
C. Reaction spontaneous at (a) and non-spontaneous at (c)
D. Reaction non-spontaneous at (a) and (b)

Strategy:
 Analyze the curvature and slope of the Gibbs Free Energy () plot versus reaction progress. The system reaches equilibrium at the minimum of the curve ().

Step 1: Point analysis
- Point (a): The slope is negative (); the reaction is spontaneous in the forward direction.
- Point (b): This is the local minimum where the system reaches thermodynamic equilibrium.
- Point (c): The slope is positive (); the forward reaction is non-spontaneous.

Step 2: Evaluate statements
- B: Equilibrium a
