Answer:
A
Explanation:
Let’s translate all the words.
simpático: likeable, kind, pleasant
antipático: disagreeable, unpleasant, mean
serio: serious
simpática: likeable, kind, pleasant (this is the feminine version of simpático, so it has the same meaning)
trabajador: hard working
The opposite of kind and agreeable (simpático)is unpleasant and disagreeable (antipático).
Therefore, the answer is A: antipático
