Correct Answer: Pleased

Solution : The correct choice is the third option.

The word disgruntled describes individuals who are unhappy, dissatisfied, or discontented, often due to perceived injustice or unfair treatment. Pleased is the opposite. If someone is pleased, he is satisfied, content, or happy with a situation.

The meanings of the other options are as follows:

• Disturbed typically implies a state of disruption, unrest, or unease.
• Determination is about resolve and perseverance, not necessarily about one's emotional state.
• Miserable conveys a sense of unhappiness or discontent.
