Directions: Read the following sentence carefully and choose the best preposition from the list below to fill in the blank
I was born _______________ San Jose _____________ California.

The correct answer is: At, in

We are required to fill in the blank with a word that indicates inclusion within a specific space. "On" means "in contact of", so option d is eliminated. Although "at" and "in" are very similar in meaning, "at" is used for a specific address and "in" is used in cases of cities and countries. San Jose is a city in the state of California, thus both these places require the use of the preposition "in". Therefore the correct answer is option a.
