Correct Answer: Mendicant

Solution : The first option is the correct answer.

An oblate generally denotes someone dedicated to religious life or service. On the other hand, a mendicant specifically describes a beggar or someone, often in a religious order, who relies on charity and takes a vow of poverty.

The meanings of the other options are as follows:

• Heathen means someone not adhering to major religions; historically, it was used for non-Christians, Jews, or Muslims.
• Layperson means non-professional; someone without specialised or professional knowledge.
• Secular means pertaining to worldly or non-religious matters; not connected to religious affairs.
