D, large arenas where services are held

Explanation:

A megachurch is a church that has 2,000 or more people in weekly attendance. Megachurches have grown in number over the years and more than half of all Americans churchgoers attend the largest 10% of churches.

Since the attendance is high, a place for worship has to be found. Megachurches services are often held in stadiums, sport arenas, football fields or in any big spaces available.

The services are very emotional and they can resemble pop concerts or a cultural event. Loud music is played, there are often visual effects and the pastors tend to be very charismatic.
