Answer to Question 1

Comets are typically first noted as the Sun's heat drives off gases, forming their coma and making them look fuzzy. Their cometary nature is then confirmed by observations of their orbital motion. Asteroids look like little stars, and thus must be found via their motion, either with them appearing as streaks on the time exposures, or analysis of digital images over time.

Answer to Question 2

B
