my father is ..... older than my mother​

The complete question is,

my father is ..... older than my mother​ ( much/more/many )

• my father is much older than my mother.

• 'Much' should be used with uncountable nouns, and should be used with singular nouns.
• 'Many' should be used with countable nouns. and should be used with plural nouns.
• 'More' defines something extra. It's different from much and many.
• Example - I need more money. ( the existing amount is not enough )
