The sentence Mon pere est plus age ___ ma mere means "My father is older ___ my mother." This question tests the comparative structure in French.
In French, comparisons of superiority use the structure: plus + adjective + que (more ... than). The word que is the conjunction that introduces the second element of the comparison.
Examples of this pattern:
Il est plus grand que son frere - He is taller than his brother
Elle est plus intelligente que moi - She is more intelligent than me
The other options do not fit the comparative structure:
et (and) is a coordinating conjunction, not a comparative connector
de (of/from) is a preposition that does not link comparative elements
comme (like/as) is used for comparisons of equality (aussi ... que) or similes, not superiority
The three French comparative forms are: plus ... que (more than), moins ... que (less than), and aussi ... que (as ... as).
