The concept of Bodhisattva is central to Mahayana sect of Buddhism, not the Hinayana sect. Therefore, statement 1 is incorrect. The Bodhisattva is indeed regarded as a compassionate one on his way to enlightenment, which makes statement 2 correct. The Bodhisattva is also recognized for delaying his own salvation, choosing instead to assist others in achieving their own spiritual enlightenment; this makes statement 3 also correct. Therefore, the correct answer includes only statements 2 and 3. Option 1 is incorrect as it only includes statement 1, which is false. Option 3 is partially correct, but leaves out the accurate statement 3. Option 4 incorrectly includes the false statement 1. As such, the correct answer is option 2, which aligns with the correct interpretation of the Bodhisattva`s role according to Buddhist tradition.
