There's nothing I like weighing in on more than a good parallelism question. Fun! This one is quite confusing because it's not possible to know WHERE the parallelism starts. It could start after "for" (i.e. "I'm responsible for my brother and my kids."), or it could start after "will be" ("I will be king of the world and a rock star!"). Or it could start after "will" (I will buy a car and go home). Because we don't know, we have to take each answer one by one. What we do know is that the SECOND item in the list is "evaluates/evaluate/evaluating" (because it comes after the parallel marker), so we need to match to that.
In addition to adhering to the policies and guidelines of the State Department of Education, the successful instructor will be responsible for instruction in the appropriate teaching environment and evaluates student learning.
will be responsible for instruction in the appropriate teaching environment and evaluates
PROBLEM: The parallel starts after "will" ("I will buy a car and drive home in it.") "Be responsible" and "evaluates" have matching tenses, but "evaluates" doesn't match ("the instructor will...evaluates" is wrong).
will be responsible for instruction in the appropriate teaching environment and evaluate
ANSWER: Same as above, except "evaluate" fits with the parallel.
is responsible for instruction in the appropriate teaching environment and evaluate
PROBLEM: "evaluate" doesn't go with the subject, so no parallel there. It also can't match instruction, because it's a verb.
is being responsible for instruction in the appropriate teaching environment and for evaluating
PROBLEM: the "being" is wrong and unparallel.
is responsible for instructions in the appropriate teaching environment and will be evaluating
PROBLEM: The change in tense is unjustifiable here. "is responsible" and "will be evaluating" should be in the same tense (there's no good reason to change. You ARE allowed to change tense in parallel if there's a good reason ("Yesterday I went to the store and tomorrow I will go again"), but there isn't one here). But we're describing two things the teachers have to do, so they should be in the same tense. In correct answer choice B, the "will" DISTRIBUTES to both verbs.
Oooo. It's an ugly correct answer choice, but I feel confident it's the best of the bunch. Hope that helps!
BTW. Remember that if you're in the present tense, the singular form of the verb has an "s" on the end (He evaluates). But if you are in the future tense, the rule changes (He will evaluate).
