C Correct answer
Explanation

The farthest human-made object, Voyager 1, is about 159 astronomical units from Earth (about 15.8 billion miles or 24 billion km). Since 1 light-year equals about 63,241 AU, this is less than 0.003 light-years - far less than one light-day (which is about 173 AU). The spacecraft have barely left our Sun's immediate neighborhood.
