Option (क) स्वाभिमान is the correct answer. When Gaya beats Moti, his anger and fierce reaction (indicated by 'मोती भी पलटट पड़ता' - Moti would have attacked back) demonstrate that he cannot tolerate being insulted and beaten. This fierce reaction to physical assault and humiliation is a clear indicator of his self-respect (स्वाभिमान). It shows that he refuses to accept subjugation quietly and protests against the unjust treatment, which is a fundamental expression of self-respect.
