Seismologists studying the earthquake that struck northern California in October 1989 are still investigating some of its mysteries: the unexpected power of the seismic waves, the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor.
(A) the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor
(B) the upward thrust that threw one man straight into the air, and strange electromagnetic signals were detected hours before the temblor
(C) the upward thrust threw one man straight into the air, and hours before the temblor strange electromagnetic signals were detected
(D) one man was thrown straight into the air by the upward thrust, and hours before the temblor strange electromagnetic signals were detected

air, and the strange electromagnetic signals detected hours before the temblor.

In option A The strange electromagnetic signala detected hours before the temblor
is not a independent clause.

so does it not lack parallelism ?

a the sentence is parallel

the unexpected power....the upward thrust....the strange signals

all have an article, an adjective and a noun

Since a colon is used any information after the colon does not have to be a complete sentence. Also, "The unexpected power of the seismic waves" is not a complete sentence

A verb is not present.
The = article
upward = adjective
thrust = noun (subject)
of the seismic waves = prepositional phrase

A it is....

coz of parallelism...."the unexpected power...., the upward thrust that..., and the strange electromagnetic signals....."

all other options are problematic.

The colon (:) signals an enumeration of the earthquakes' mysteries. Only A makes a simple and parallel enumeration.

Answer: A
