The answer is (D.) 225, 000, 000 km

AU means astronomical unit. It is used by the astronomers to measure large distances in the Solar System. 1 AU is the average distance from Sun to Earth which is 149, 598, 000 km.

So to get the km value of 1.5 AU.

1.5 x 149, 598, 000 = 224, 397, 000

Round off to 225, 000, 000

Answer: D. 225,000,000km

Explanation:

An Astronomical Unit is the average distance between the Earth and the Sun. It is a unit of length which is used to measure distances in our galaxy.

1 astronomical unit is approximately equal to 150 million kilometers. 1 million is \(10^6\).

Thus  1 Astronomical unit (AU)  is equal to 150 million km or \(150\times 10^6km\)

So 1.5 Astronomical unit (AU)=\(\frac{150\times 10^6}{1}\times 1.5=225\times 10^6km=225000000km\)

Thus correct option is D.
