The correct option is 2 only
Explanation
The Lakshmana Temple at Khajuraho is one of the finest examples of the Nagara style of temple architecture, specifically belonging to the Chandella dynasty. It is renowned for its fully developed architectural plan and intricate sculptures.
Statement 1 is Incorrect:
The temple is dedicated to Lord Vishnu. The central sanctum houses an image of Vaikuntha Vishnu (a three-headed and four-armed form). It was built by the Chandella King Yashovarman in the 10th century CE.
Statement 2 is Correct:
The Lakshmana Temple follows the Panchayatana style of architecture. In this layout, the main shrine is surrounded by four smaller subsidiary shrines at the corners of the raised platform (Jagati). Therefore, it is not a single-shrine temple.
Statement 3 is Incorrect:
As a classic Nagara style temple, its shikhara (tower) is curvilinear and is topped by a large, ribbed circular stone disk called an Amalaka, surmounted by a Kalasha (finial). A stupa-like dome is not a feature of the Nagara style; such domes are characteristic of Buddhist architecture or later Indo-Islamic styles.
Key Takeaway:
The Lakshmana Temple is a Panchayatana (five-shrined) Nagara temple dedicated to Vishnu, characterized by a curvilinear shikhara topped with an Amalaka, not a dome.
