Rectus femoris indeed originates from the anterior inferior iliac spine, making it unique among the quadriceps muscles as it crosses both the hip and knee joints, allowing it to act on both. The other options are incorrect: Vastus lateralis does not insert on the tibia but rather the patella via the quadriceps tendon, all four muscles primarily extend the knee rather than flex the thigh, and vastus medialis originates from the medial side of the femur, not the lesser trochanter.
