Sentence correction paralellism issue

[amateur]

The plantation owners are a worried lot because the rains are just around the corner and neither the topsoil has arrived nor have the plants

A) neither the topsoil has arrived nor have the plants
B) neither the topsoil has arrived nor the plants
C) neither the topsoil nor the plants has arrived
D) neither of the topsoil or plants has arrived
E) neither has the topsoil nor the plants have arrived
Source: Aristotle GMAT SC Grail page184 question6

Explanation given: Since the verb has arrived after neither in the sentence, we need to repeat the verb after nor. I eliminate B, C, D for obvious reasons. Between A and E I chose E. OA says A and eliminates E because "to get the parallelism correct the part after nor should read - nor have the plants arrived."
If this is the case, even in A, for parallelism to happen shouldn't the answer choice read - neither the topsoil has arrived nor the plants have

After following MGMAT verbal SC, I was looking for neither the topsoil nor the plants have arrived option. I must have been happy if I saw that option :)

On the same ground, a question on the next page
Jerry knows it is futile to convince his wife to buy the beach house because she is neither fond of swimming nor does she like to surf
A) She is neither fond of swimming nor does she like to surf
B) she is neither fond of swimming nor of surfing
C) she is neither fond of swimming nor surfing
D) neither is she fond of swimming nor of surfing
E) neither is she fond of swimming nor does she like to surf
Even in this case fond is a verb, right? fond is appearing after neither. So shouldn't found be repeating after nor? neither.. nor is a parallelism operator so I test myself that the correct answer will have two clauses (after neither and after nor) that make complete sentence with the remaining part of sentence. So in this case, how can B be the right answer without fond in the second part (after nor)? Please explain. Thank you

This source is banned here, because its problems are consistently of poor quality.
In these two examples, both purportedly correct answers are actually wrong, for largely the reasons you've stated here (although "fond" is a modifier/adjective, not a verb).

Don't use this source.
