Answer to Question 1

B

Answer to Question 2

The more massive the star, the faster it evolves, and less time it has to leave its stellar nursery and dense molecular cloud. When it explodes while still close to this dense region, its shock wave will trigger compression and collapse of many smaller protostars all at once.
