PIO OCI eligibility

[nikreations]

Hello,
I need help in deciding my wife & son's eligibility for PIO & OCI... very confused on the rules:

Me: Indian Citizen permanently residing in UK for 10 years (holding Indian Passport).

Wife: Non-Indian Origin, British Citizen.

Us: Married for 7 years.

Son: 11 months old, born in UK, holding British Passport.

1. Is my wife eligible for PIO Card as a spouse of Indian Citizen?

2. Is my son eligible for OCI Card as a son of Indian Citizen?

3. Is my son eligible for PIO Card as a son of Indian Citizen?

Thanks for your help.
