ATS does not transfer from utility to generator

[cjones09]

An ATS does not transfer from utility to generator. The generator is running and producing voltage. Which of the following is the cause of it not transferring?
A) The breaker feeding the ATS did not open
B) battery does not have enough charge to operate the ATS
C) Frequency of the generator is too low
D) Service only lost one phase

Looking for help on this question. These are my thoughts, what do you think?

A. This could be possible, the question doesn't state if the utility available light is still on or not
B. Not sure what type of ATS we are dealing with
C. Question doesn't specify the application but I would think any sync issues would be resolved at the gen switchboard
D. This would be a cause for transfer, so this answer is probably incorrect

Thanks in advance.

An ATS does not transfer from utility to generator. The generator is running and producing voltage. Which of the following is the cause of it not transferring?
A) The breaker feeding the ATS did not open ATS is an OPEN TRANSITION transfer, the breaker isn't supposed to open
B) battery does not have enough charge to operate the ATS Since when do batteries operate an ATS?
C) Frequency of the generator is too low ATS controllers monitor generator frequency.
This is probably the correct answer
D) Service only lost one phase This is a reason to initiate a transfer. This doesn't explain why it didn't transfer
