Hello! I need the answer of attached question. Also, I need a short explaination about why it should be like that. Thanks!

Selected Response: Circle the best answer (a -d or e) to each question.
1. Consider the boiling points of the binary Group 14 hydrides. Choose the relative ranking
(I or II), the evidence you are using to make this claim (III, IV, or V), and the reasoning (VI
or VII) that allows you to make this claim.
Relative Rank (I or II):
CH< SiHa < GeHa < SnH4
SnH4 < GeH4 < SIH4 < CHA
Evidence:
II. Ranking I is based on the total number of electrons.
IV. Ranking II is based on the molecular mass.
V. Ranking Il is based on the structure of species.
Reasoning:
VI. The greater the number of electrons the more polarizable an atom or molecule.
VII. Heavier atoms and a larger structure will lead to a larger AS°.
VIII. Polarizable atoms have stronger dispersion interactions.
a. I, II, VI
b. I, II, VI, VIII
c. II, IV, VII
d. II, V, VII
e. II, V, VIII
