Does a Planet's Location Within the Milky Way Galaxy Affect

Multiple Choice

Does a planet's location within the Milky Way Galaxy affect the likelihood of evolving life on the planet?

A) No. As long as a star is nearby the chances for the evolution of life would not seem to depend on the rest of the Galaxy.
B) Yes. The closer to the center of the Galaxy a planet is, the greater will be the density of stars. Being bathed in large amounts of light should increase the possibilities of the evolution of life.
C) Yes. A planet on the outer edge of the Galaxy would be susceptible to radiation from outside the Galaxy because it would not be protected by the galactic magnetosphere. Chances for life would not be good.
D) Yes. Stellar systems too far from the galactic center are deficient in metals. Such elements are necessary to build Earthlike planets and life as known.
