The aircraft is equipped with two Integrated Avionics Computers, named IAC1 and IAC2.

• A. The aircraft is equipped with two IACs, IAC1 and IAC2.
• B. The aircraft has three IACs: IAC1, IAC2, IAC3.
• C. The aircraft uses no IACs.
• D. The IAC units are not used for display control.

Answer: (A)

The statement reflects the exact setup given: there are two Integrated Avionics Computers, named IAC1 and IAC2. That means the aircraft is equipped with two IACs and their identities are IAC1 and IAC2, which is precisely what the description asserts. The other possibilities don’t fit because they either add an extra IAC (IAC3 would be introduced), claim there are none (which would contradict the named IAC1 and IAC2), or deny the role of IACs in display-related tasks (integrated avionics are involved in managing cockpit displays).
