Well, let's see whether there are any mistakes in the sentences:
A. Who is Marys teacher this year? here we're missing an apostrophe,the correct sentence would be: A. Who is Mary's teacher this year?
B. Last summer, we visited California. -this is the correct answer!
C. My doctors name is Dr Habeeb. Again, a missing apostrophe! it should be: My doctor's name is Dr Habeeb.
D. Jennifer bought cupcakes diet soda and potato chips at the store.
Here we are missing a comma, like this: Jennifer bought cupcakes, diet soda and potato chips at the store.
The sentence that contains correct capitalization and punctuation is B) Last summer, we visited California. A should be - Who is Mary's teacher... C should be - My doctor's name is Dr. Habeeb. D should be Jennifer bought cupcakes, diet soda, and potato chips at the store.
