Composition of the Authority is dealt with in which section?

Section 4 is the correct answer. After an authority has been established (as typically occurs in Section 3), the immediate next logical step in legislative structure is to detail its composition, outlining who its members are and how it is structured. This provides clarity on the body's makeup.

• Section 3 deals with the establishment of the Authority itself.
• Section 7 and Section 8 would typically cover other operational aspects, powers, or functions of the Authority, not its fundamental composition immediately after establishment.
