Correct Answer: Meddle

Solution : The correct choice is the first option.

Explanation : The aim is to find a word that conveys the idea of getting involved in or interfering in others' affairs. Meddle is the appropriate synonym, as it means to intrude or interfere in a situation without invitation or necessity.

The meanings of the other options are as follows:

• Speak : This refers to the action of talking or expressing oneself verbally and is not synonymous with the idea of intervention.
• Trouble : This means to cause distress or problems, not necessarily to intervene in others' affairs.
• Help : This means to assist or aid, and it is the opposite of intervening negatively in others' matters.

Therefore, the correct sentence would be: "Syam does not meddle in others' affairs."
