Solution

The correct option is A
Always Parallel

In a parallelogram, opposite angles are equal which means, $∠ A$ = $∠ C$ .

Then, $\frac{1}{2}$ $\times$ $∠ D A C$ = $\frac{1}{2}$ $\times$ $∠ A C B$

Thus, $∠ E A C$ = $∠ A C F$ , which are alternate interior angles.

Hence, AE and CF are parallel lines.

The correct option is A Always Parallel In a parallelogram, opposite angles are equal which means, ∠A = ∠C. Then, 12 × ∠DAC = 12 × ∠ACB Thus, ∠EAC = ∠ACF, which are alternate interior angles. Hence, AE and CF are parallel lines.
