Answer:

Explanation:

The correct option should be B.

The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.

Mathematically, in astronomy,

1 astronomical unit = 150,000,000 km

But then, 1 km = 0.621371 mile

Hence,

150,000,000 km = 150,000,000 x 0.621371 miles

≈93,000,000 miles

Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.

The correct option is B

The Hypothetico-Deductive method is a scientific model of reaserch. You make a hypothesis of what the problem is - keep in mind that, according to Einstein's thoughts, these hypothesis cannot be 100% verified, they can only be proven wrong - and once you have that, do deduce what the consequences might be.
