In the Ramayana, the demon Maricha (uncle of Ravana) took the form of a golden deer to distract Rama and lure him away from Sita. While Rama was chasing the deer and Lakshmana had gone to help him, Ravana kidnapped Sita. The other options are wrong: Ravana was the kidnapper who ordered the deception, Tataka was a demoness killed earlier by Rama, and Mandodari was Ravana's wife.
