yup, B for parallelism.

A may mislead at first glance coz of "causing" . IMO, "causing a rise... eye disease" works as a participle phrase to clarify how the radiation "endanger human health" rather than forms a parallel action to " endanger" ---> its gerund form can't be counted in the parallelism.

"threaten ...." must be parallel to "endanger" --> threaten must be in infinitive form ---> A and D out for the use of "threatening" ... C and E out for the use of the noun form of "threat" .

B stands the best.
