Which of the following elements is often found at the entrances to Egyptian temples?

Obelisks are tall, four-sided, narrow tapering monuments that typically have a pyramidion at the top. They were often placed at the entrances of ancient Egyptian temples as a way to honor the gods and commemorate significant events or individuals. These structures symbolize the connection between the earth and the sun, reflecting the Egyptians' reverence for both the divine and the solar deity Ra. The presence of obelisks at temple entrances served not only a decorative purpose but also conveyed the power and influence of the pharaohs who commissioned them.

In contrast, domes and oculi are architectural elements more commonly associated with later periods and different cultures, specifically in Roman or Byzantine architecture. A transept is a feature found in some Christian church designs, which allows for a cross-shaped layout, but it is not relevant to Egyptian temple architecture. This context highlights the significance of the obelisk as a quintessential symbol of ancient Egyptian temples and their religious practices.
