Answer:
Correct option is D: Community gardens began in 1998, which resulted in a positive environmental impact on neighborhoods across the nation.
Explanation:
The most format style of a sentences is shown in option D because it provides great meaning without too much full-stops and avoid parallel errors. In option A and B, there are too many stops and almost meaningless phrases standing alone. Option C would have been a good option, but using "so" after the comma and "worry about getting good" and "healthy stuff to eat" makes it informal.

Dear Friend!
How are you? I am very fine here. I want to share my experiences that I had during our summer vacation. Our examinations were hectic and I really needed to relax myself. This vacation was a boon to me as I was able to enjoy as well as learn something new. My grandparents took me on a trip to Shimla for three days and the climate was really snowy. It was the first time that I ever saw snow. I had a lot of fun skiing and playing with the snow. After that, I enrolled for computer classes for 5 days. I was taught about how to use adobe Photoshop and other related tools. The classes were very interesting and I feel that you will like it too. I will share my experiences with you at school. I am waiting to see you my friend.  
Hoping to hear from you.
Take care!
Yours Lovingly,
