Which sentence is written correctly?

a. ever since i was a teenager, i have loved going to the theater.
b. although the lasagna looked terrible, it tasted wonderful.
c. pepper and i decided it was time to head home.
d. while jonathan was napping, i finished doing the dishes.

The correct sentence that is written correctly is: A) Ever since I was a teenager, I have loved going to the theater.

Here are why the other options are wrong:

B) 'although the lasagna looked terrible, it tasted wonderful.' <-- "although" is not capitalized at the beginning of the sentence. If it's the start of a sentence, you have to capitalize the first letter of the first word. 

C) 'Pepper and i decided it was time to head home.' <-- The issue with this is that the sentence does not capitalize "I". Nobody really knows why "I" needs to be capitalized since it is a first person pronoun. 

D) 'while Jonathan was napping, I finished doing the dishes.' <-- "While" is not capitalized at the beginning of the sentence, making it improper.

B. alice is pretending there is a way through the glass when in reality that would not be physically possible therefore she has to pretend. but i think d is also possible because alice notices the glass is actually melting away which is also not possible either
