"because the fruits are first rate"
Here's why the other segments are incorrect:
* "my family including gram" - "Gram" should be capitalized as it's a proper noun, likely a nickname for "Grandma" or "Grandmother".
* "shops at produce market" - "Produce market" should be capitalized because it's the name of a specific place.
