Which hydraulic systems provide pressure to the brakes?

Explanation:
Brakes on the CRJ-550 are powered by two independent hydraulic circuits to provide redundancy. The pressure that operates the wheel brakes comes from System 2 and System 3. System 1 serves other hydraulic functions (such as different flight controls and gear-related systems) and does not feed the wheel brakes. In normal braking, pressure from both System 2 and System 3 is used, so if one system loses pressure, the other can still provide braking, though performance may be reduced. This redundancy is why the correct answer points to System 2 and System 3.
