Answer to Question 1

B

Answer to Question 2

The higher the mass, the greater its gravity, so the faster it shrinks and heats up to reach the main sequence. Once there, it will fall to the top left of the H-R diagram, and as a spendthrift star, rapidly deplete its supply of hydrogen and leave the main sequence, evolving into a red giant such as those that dominate the globular clusters.
