Option b is the correct answer. Jayasimha Siddharaja, a ruler of the Chaulukya dynasty, granted financial aid for the restoration of a demolished mosque in Khambhat. Jayasimha was known for his religious tolerance and impartiality towards various sects and religions. He extended his support to rebuilding the mosque after communal clashes in Khambhat led to its damage. This act of generosity, as documented by the Muslim author Minhaj-i-Siraj in his book Tabaqāt-i-Nasiri, reflects Jayasimha Siddharaja's commitment to fostering harmony among different religious communities and his dedication to promoting coexistence and understanding.
