The prongs of a tuning fork, acting like the strings of a musical instrument,produce ripples in the air flowing over them when struck against a surface;the resulting flow pattern,with stationary crests and troughs although they are formed by rapidly moving air,is known as 'standing waves'

the resulting flow pattern ....... is
the subject verb agreement eliminates C,D and E
'Although' is a subordinate clause which require a main clause to attach to.
(A) lacks a main clause before 'although'
Additionally, (B) is using the active form instead of the passive voice in (A)
IMO 'B'

(A) stationary crests and troughs although they are formed by rapidly moving air,is --> contrast is lost between "rapidly moving" & "stationary" or clause is missing before "although"
(B)crests and troughs that remain stationary although the air that forms them is moving rapidly,is --> correct
(C) crests and troughs that remain stationary although the air that forms them is moving rapidly,are --> "pattern" is singular
(D) crests and troughs that remain stationary although they are formed by rapidly moving air,are --> same as C
(E) stationary crests and troughs although the air that forms them is moving rapidly ,are--> same as C
