Look at the pictures and choose the correct option that should be in capital letter.

my mother is a good cook

The correct answer is: My

Here, 'M' in 'my' will be in capital letters because we know that anytime we use proper nouns (person, place, organization, or thing) or whenever we are starting a sentence we are supposed to use a capital letter. Since here we are starting the sentence with 'my' we will use a capital letter.
