Find the odd place (place of worship vs public venue): Identify the one that is not a place of worship.

Introduction / Context:
Public places can be grouped by function. Three of the options are religious places of worship, while one is a secular entertainment venue. Function is the decisive attribute here.

Given Data / Assumptions:

• Temple: place of worship.
• Mosque: place of worship.
• Church: place of worship.
• Theatre: venue for performances/films, not a religious site.

Concept / Approach:
Classify by primary social function. Religious worship vs secular entertainment creates a clear, non-overlapping partition.

Step-by-Step Solution:

Verification / Alternative check:
Consider typical activities: prayer and rituals vs watching plays/movies.

Why Other Options Are Wrong:
They share the religious function and thus form a coherent group.

Common Pitfalls:
Spelling variations (theatre/theater) do not change the function.

Final Answer:
Theatre
