C.
a computer program that shows how the Sun changes over time
OD. a paragraph that describes the Sun's structure
E

E

Explanation:

The question talks of a PHYSICAL model of the sun. An equation, chart, computer program and paragraph are most definitely not physical models.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
