Explanation:

Question 16

The ecliptic is the apparent path of the Sun across the sky, along which zodiac constellations lie. "Circus" is unrelated, "Ellipsis" is a punctuation or geometric term, and "Zodiac" is the group of constellations, not the path.

Galileo Galilei was the first to use a telescope for scientific astronomical observations, discovering moons of Jupiter, lunar craters, etc. Ptolemy, Moses, and Hipparchus did not use telescopes for science.

Zodiac constellations were originally used as a calendar to track time/season via Sun’s position. Religious use, navigation (not primary original), and matchmaking are incorrect.

Answer:

b. Ecliptic
