+1 for B.

B. employing deflagrations rather than detonations, were --> Correct usage of plural verb 'were', and is parallel i.e, A rather than B.

Hence, B.

Sub-Verb Pair:
.In a recent wave engine study, simulations of a pulsejet, a related device
.that employs deflagrations rather than detonations
. was also performed

Sub-Verb no. agreement: Plural(simulations of a pulsejet)-singular(was) ---> X
Verb Tense: Simple Present- fact ---> correct
Modifier: a related device that employs deflagrations rather than detonations ---> X (device does not employ but contains)
Idiom: X rather than Y - deflagrations rather than detonations ---> correct

A. that employs deflagrations rather than detonations, was - Incorrect based on the above analysis

B. employing deflagrations rather than detonations, were - Bingo

C. employed to deflagrate rather than detonating, were - X and Y not parallel

D. the employment of which entails deflagration rather than detonation, were - the "employment of which", unneessary wordy also "which" needs a comma before the noun or noun modifier that it modifies

E. that employs deflagrating rather than detonation, were - X and Y not parallel
Option B
