The ans is indeed D
First a 3-2 split
Students in the early 1960s were taught X and Y.(X & Y should be parallel)
X--->that electrons orbit the nucleus of an atom
look at X---the tense is present ......so Y should start with 'that' and should be in present tense.
Y--->that the path of this orbit is circular.
Hope this helps.....criticisms are welcome:laugh:
Thanks Ashish, for your post.
1) if you don't mind please clarify what is 3-2 split.
2) why did u prefer it that way - " Students in the early 1960s were taught
X and
Y."
can't we break it like this - " Students in the early 1960s were taught that
X and
Y." now also
X and
Y can be parallel as in my previous post.
moreover, i was surfing the net.. i found something regarding "
omitting that" which i think is worth sharing.

The word
that is used as a conjunction to connect a subordinate clause to a preceding verb. In this construction
that is sometimes called the "expletive
that." Indeed, the word is often omitted to good effect, but the very fact of easy omission causes some editors to take out the red pen and strike out the conjunction
that wherever it appears. In the following sentences, we can happily omit the
that (or keep it, depending on how the sentence sounds to us):
- Isabel knew she was about to be fired.
- She definitely felt her fellow employees hadn't supported her.
- I hope she doesn't blame me.
Sometimes omitting the
that creates a break in the flow of a sentence, a break that can be adequately bridged with the use of a comma:
- The problem is, that production in her department has dropped.
- Remember, that we didn't have these problems before she started working here.
As a general rule, if the sentence feels just as good without the
that, if no ambiguity results from its omission, if the sentence is more efficient or elegant without it, then we can safely omit the
that. Theodore Bernstein lists
three conditions in which we should maintain the conjunction that:
- When a time element intervenes between the verb and the clause: "The boss said yesterday that production in this department was down fifty percent." (Notice the position of "yesterday.")
- When the verb of the clause is long delayed: "Our annual report revealed that some losses sustained by this department in the third quarter of last year were worse than previously thought." (Notice the distance between the subject "losses" and its verb, "were.")
- When a second that can clear up who said or did what: "The CEO said that Isabel's department was slacking off and that production dropped precipitously in the fourth quarter." (Did the CEO say that production dropped or was the drop a result of what he said about Isabel's department? The second that makes the sentence clear.)
