Question

A. space-26-mcq-04 boundary: expanding-universe balloon model correctly supports (Physics only) Distinguish a galaxy from the universe by using contrast, separate, misconception, not in Our Solar System.
B. space-26-mcq-04 orbitrotation error: this swaps orbit with rotation and misses boundary reasoning.
C. space-26-mcq-04 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
D. space-26-mcq-04 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.

Answer

The correct option is space-26-mcq-04 boundary: expanding-universe balloon model correctly supports (Physics only) Distinguish a galaxy from the universe by using contrast, separate, misconception, not in Our Solar System.

Explanation

space-26-mcq-04 boundary: expanding-universe balloon model correctly supports (Physics only) Distinguish a galaxy from the universe by using contrast, separate, misconception, not in Our Solar System. It links expanding-universe balloon model to the exact learning objective instead of drifting into a nearby astronomy idea. Red shift means light from distant galaxies has increased wavelength; together with cosmic microwave background radiation it supports an expanding universe from the Big Bang. The distractors fail through orbit-rotation confusion, scale mixing, or missing evidence. Unique focus tokens: contrast separate misconception not confuse whereas unlike comparison limit.
