Yes, you are correct! The earliest solar system model to exist was the Ptolemaic model, represented by option D. The Ptolemaic model was developed by Claudius Ptolemy and was a geocentric model, meaning it placed the Earth at the center of the universe and had all the celestial bodies, including the sun and planets, orbiting around it.

Sure! I'd be happy to help explain how to arrive at the correct answer.

To find the earliest solar system model, we need to look at the historical order in which these models were developed.

The Ptolemaic model, also known as the geocentric model, was the earliest solar system model among the listed options. It was developed by Claudius Ptolemy in the 2nd century CE. According to this model, the Earth was believed to be at the center of the solar system, with other celestial bodies, including the Sun, the Moon, and planets, orbiting around it.

On the other hand, the Aristotelian model was proposed by Aristotle in the 4th century BCE. It was not explicitly a solar system model but described the Earth as a stationary object at the center of the universe, with other celestial bodies moving in circular motion around it.

The heliocentric model, which states that the Sun is at the center of the solar system, was proposed by Nicolaus Copernicus in the 16th century CE. This model revolutionized our understanding of the solar system and challenged the geocentric view.

So, considering the chronological sequence in which these models were proposed, the correct answer is:

d) Ptolemaic

I hope this explanation helps! Let me know if you have any further questions.

Nope. The earliest model was Greek.
