Answer:
B. Largest gravitational attraction
Explanation:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
I beleive it's B because it would have to be a strong gravitational pull to keep everything balanced correctly.
Please mark me brainliest if correct :)

Answer:
False
Explanation:
Phylogenetic analysis is a means of establishing evolutionary relationships.
Synapomorphy is a shared ("syn") character that is different from the form found in an ancestor that distinguishes a clade (monophyletic group)from other organisms
The absence of a trait can be used as a synapomorphy in phylogenetic analysis. For example, the loss of a trait, such as the loss of legs in snakes, can be a valuable synapomorphy for a clade.
