Answer:
The beautifully decorated buidings where Muslims go to worship are known as Option C) mosques.
Step-by-step explanation:
A mosque is a Muslim place of worship. Although Muslims are not obligated to perform their daily prayers in an official mosque (they can do the 5 prescribed daily prayers anywhere they happen to be), all men are expected to gather at the Jami Masjid, the main mosque of a city for the Friday prayer at noon. People use mosques throughout the week as a place to reflect or to study or for prayer.
