, choose the correct answer.

**(A)**

**(B)**

**(C)**

**(D)** Only **(A)** and **(B)** are correct

**(E)** **(A)**, **(B)** and **(C)** are correct.

It is given to us that .

** (, alternate interior angles are equal) (1)**

And, ** (, alternate interior angles are equal) (2)**

From** (1)** and **(2)**, we get

We have **(, sum of co-interior angles is equal to ) (3)**

And, **(, sum of co-interior angles is equal to ) (4)**

From **(3)** and **(4)**, we get

Similarly,

**(, sum of co-interior angles is equal to )**

Hence, the answer is **(E)**.
