Due to the change in the number of electrons, the metal and nonmetal atoms both become

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
