I am confused on the rules surrounding this problem. Were is plural. And was is singular.
But now that I think about it I suppose “were” is appropriate for the plural simulations.
My only other issue was decided between “employs” or “employing” and why the later is the correct form.

Question Stem: In a recent wave engine study, simulations of a pulsejet, a related device that employs deflagrations rather than detonations, was also performed.
Error: Here, stem talks about `simulations` and should be `were` performed as plural.
A. that employs deflagrations rather than detonations, was
- Was is wrong
B. employing deflagrations rather than detonations, were
- Correct. `Were` is used, and `deflagrations and detonations` is parallel.
C. employed to deflagrate rather than detonating, were
- Wrong. `deflagrate and detonating` is not parallel.
D. the employment of which entails deflagration rather than detonation, were
- Wrong. `employment of which entails` is wordy and unnecessary
E. that employs deflagrating rather than detonation, were
- Wrong. `deflagrating and detonation` is not parallel.
