The correct answer is A. Both societies had an advanced understanding of astronomy.
Explanation
Astronomy was one of the disciplines in which Maya civilization stood out because they created their own solar calendar and the identification of solar eclipses, in addition, their studies on the movement of the celestial bodies allowed them to know the lunar cycles. Similarly, Egyptian astronomy had important developments on astronomy because there was related to religion, for example, its main God Ra, was associated with the sun, also focused on the observation of the stars, an evidence of this is that the pyramid of Gizeh is aligned with the star polar. So, the correct answer is A. Both societies had an advanced understanding of astronomy.
The 2nd and 3rd answers are wrong for sure. Leaving you with 1st and 4th. Mayans did not mummify their dead. Mayans also practiced human sacrifice. That knocks 2 answers out. Personally, I'd go with the 1st choice as they both had an understanding and used the stars/planets as clocks, events, etc.<span />
