Correct Answer: Satisfy

Solution : The correct choice is the fourth option .

Annoy means to disturb or irritate someone, causing them to feel bothered or frustrated. Satisfy is the antonym because it means to fulfil or meet someone's needs or desires, leading to contentment or fulfilment rather than causing irritation or disturbance.

The meanings of the other options are as follows:

• Graze : This means to feed on growing grass, referring to animals feeding on pasture.
• Mystify : This means to perplex or bewilder someone, causing confusion or puzzlement by making something mysterious or difficult to understand.
• Employ : This means to use or engage in something, such as employing a tool or method for a particular purpose.
