Answer to Question 1

A

Answer to Question 2

No. Mars is small, and even at closest approach it is so distant from Earth that it takes large telescopes with the best conditions to resolve surface features as small as 100 km across. With the unaided eye, Mars appears as a small point of reddish light shining more brightly than the stars.
