All the choices are correct?

were present... I think

YL is correct.

DP is.......

As a correlative conjunction, neither is almost always followed by nor, not or: Neither the liberals nor the conservatives had originally supported the winner. Subjects connected by neither … nor take singular verbs and pronouns when both subjects are singular (Neither Diane nor Nicole has her own apartment), plural when both are plural: Neither the Yankees nor the Dodgers got much help from their bull pens that year.

So WAS is correct.

Usage guides commonly say that when a singular and a plural subject are joined by these correlative conjunctions, the noun or pronoun nearer the verb should determine the number of the verb: Neither the mayor nor the council members have yielded on the issue. Neither the council members nor the mayor has yielded on the issue. Practice in this matter varies, however, and often the presence of one plural, no matter what its position, results in a plural verb.

In edited writing the construction following neither is parallel to the one following nor: The great days of American political oratory are neither dead nor waning (not neither are dead nor waning). This sale sacrifices neither quality nor availability (not This sale neither sacrifices quality nor availability).

Although some usage guides say that neither may introduce a series of no more than two, it often is used to introduce a series of three or more: The head of that department is neither skillful nor well-prepared nor honest. See also either.

Hi Mame

I think you've misunderstood my question. I was asking whether all the options provided are correct, not the usage of 'neither... nor'?

However, I would like thank you for the notes on its usage.

Best wishes

Only the "neither... nor" option is correct.

And if you'd read the blurb I posted, you would have seen that. I did BOLD the appropriate bits. It pays to think for yourself sometimes, which is why I post these things for you.

No offense meant, but it was there in black and white.

Yes, and my rather short post told him what he wanted to know.

To make sure that I get the correct interpretation of your reply, was I right to say that all the choices are correct.

I'm sorry, I made a mistake due to not reading the answer (or the question) closely enough.

(3) is correct.
(1) is wrong.
(2) could be considered as correct, but in my opinion for it to be completely correct the verb "was" would have to be plural "were" because it refers to two of them.

So IMO (3) is the only correct answer.

Thanks, Mc Tag.

It is clear now.
