The principles of roman catholicism require followers to do all of the following except: a. recognize the pope's authority. b. worship the holy trinity. c. perform 11 sacraments. d. attend mass weekly.

The answer that doesn't belong in the list:

c. Perform 11 sacraments

In Roman Catholicism, there are seven sacraments, of which an individual has access to six. Entering Holy Orders (as a monk or nun or priest) is a sacrament -- and celibacy is an expectation of those who enter Holy Orders. Marriage is also considered a sacrament. So an individual Catholic does not access both of those sacraments, but one or the other ... or neither (if the individual remains unmarried but does not enter Holy Orders).

In addition to Holy Orders and Marriage, the other five sacraments observed in Roman Catholicism are:

Baptism

The Eucharist (Lord's Supper), offered in the mass

Reconciliation (formerly called the Sacrament of Penance)

Confirmation

Anointing of the sick (which has sometimes been called Extreme Unction)
