The possible long-term health risks to airline personnel who repeatedly cross multiple time zones has been a concern since the first jet transports went into service in the 1950s.

A)who repeatedly cross multiple time zones has been a concern since the first jet transports went
B)who are repeatedly crossing multiple time zones has been a concern since the first jet transports that went
C)who repeatedly cross multiple time zones have been a concern since the first jet transports went.
D)repeatedly crossing multiple time zones has been a concern since the first jet transports went
E)repeatedly crossing multiple time zones have been a concern since the first jet transports going

There is a split who vs repeatedly. Can we please discuss them.

In A, B and D, has (singular) does not agree with risks (plural).
Eliminate A, B and D.
.
E: repeatedly crossing
Here, the usage of crossing implies an action that happens CONTINUOUSLY, while the usage of repeatedly implies an action that happens OFTEN.
It is illogical to say that a CONTINUOUS action happens OFTEN.
Eliminate E.

The correct answer is C.

concerns.... "have".... plural

C and E remain..

jets went into service in the 1950's... is correct.. so C...

in E.. jets "going" into service is wrong as the action of going into service is finished in the past.. so using presnt continuous form there is wrong..
