Naturalisation query for ILR spouse

[jrs1984]

Now that I have my ILR granted in Jan'23 and my son applying MN1, only my wife remains. She is on PBS and will complete her 10 years in UK in Mar'24. Assuming that I am able to apply successfully for naturalisation by her Set LR eligibility, what would be the route available for my wife -
a) Will she have to get ILR first and wait 1 year for naturalisation, OR
b) Once getting ILR, can she directly apply for naturalisation without 1 year wait, assuming I become a British citizen by then, OR
c) There won't be any need for ILR, and she can directly apply for naturalisation once I become British citizen.

My guess would be "a)" like the route I am in, but not sure.

a. No need to wait 1 year provided she meets the citizenship requirements.

b. Yes

c. She needs ILR first.
