Which sentence is written correctly? a. while jonathan was napping, i finished doing the dishes. b. although the lasagna looked terrible, it tasted wonderful. c. pepper and i decided it was time to head home. d. ever since i was a teenager, i have loved going to the theater. mark for review (will be highlighted on the review page)

The correct answer is D. Ever since I was a teenager, I have loved going to the theater.
A is incorrect because the word while is not capitalized - and it should be because it is the beginning of a sentence.
B is incorrect for the same reason - the word although should be capitalized because it is found at the beginning.
C is incorrect because the pronoun I needs to be capitalized. 
Only sentence D is completely correct.
