Is this a book or no cause you made it sound very confusing
If I am not mistaken, I believe it should be 'A', if you meant "the gold and brown puzzle pieces are on the cats head" not "the gold and brown puzzle pieces are the cat's head".
It illustrates the need for maintaining equality in a society.
Your question has been heard loud and clear.
To become an engineer , all you truly need is the will to become an engineer , the interest for it. Whether or not you take english literature , doesnt matter , bc all you need is the skills and will to conquer your dream.
Thank you
