+1 for E.

A. have marked the servicing and maintaining

C. have marked the service and maintenance

E. has marked the servicing and maintenance --> Correct, rectifies S-V error, and entities are parallel 'the servicing and maintenance'

Hence, E.

A. have marked the servicing and maintaining

"A pattern" is singular subject and requires a singular verb "has" INCORRECT

B. have marked the servicing and maintenance

"A pattern" is singular subject and requires a singular verb "has" INCORRECT
________________________________________________________________________________________________________________

C. have marked the service and maintenance

"A pattern" is singular subject and requires a singular verb "has" INCORRECT
________________________________________________________________________________________________________________

D. has marked the service and maintaining

"maintaining" of new power plant doesn't sound correct, it should rather be "maintenance" INCORRECT
________________________________________________________________________________________________________________

E. has marked the servicing and maintenance

"servicing and maintenance of" sounds idiomatic.
________________________________________________________________________________________________________________

Hence option E

The difference between D and E is that "maintaining of new plant" doesn't sound correct while "servicing" alone is ok. To be 100% precise "service and maintenance" would be best option
