Final answer:
A (C) minaret is a tower from which the call to prayer is issued in Muslim religious architecture, visible as part of mosque designs, and it is where the muezzin recites the adhan.
Step-by-step explanation:
The tower from which the call to prayer is issued in Muslim religious architecture is known as a minaret. A minaret is a tall, slender tower attached to a mosque, and the muezzin recites the adhan (call to prayer) from it. This architectural feature is designed to be one of the most visible parts of a mosque, symbolizing connection with the divine.
Mosques are also known to have mihrabs, which are niches indicating the direction of Mecca, called the qibla. The faithful pray toward the qibla wall where the mihrab is set. Other architectural elements of mosques can include domes or a madrasa, which is an educational institution, but the key distinguishing feature related to the call to prayer is undoubtedly the minaret.
