Which variants are designated under the Lightning II JSF?

Which variants are designated under the Lightning II JSF?

• A. B and C
• B. A and C
• C. A and B
• D. B and D

Answer: (A)

The important idea is that the Lightning II is a family of aircraft, not a single airplane. The F-35 Joint Strike Fighter comes in three variants to fit different services and missions: the F-35A, the F-35B, and the F-35C. The A model is the conventional takeoff and landing version used by the Air Force, the B model is the short takeoff/vertical landing version used by the Marine Corps, and the C model is the carrier-capable version used by the Navy. Because it’s a family, all three variants are designated under the Lightning II JSF. The question as written lists pairs of variants, so no single option captures the full set of three. The correct understanding is that the complete designation includes all three variants, with B and C being two of them and A being the third.
