Explanation:

- Statement 1: Parmahansa Mandali was not founded by Swami Vivekananda, nor was it founded in Bengal. It was established in 1849 in Bombay (now Mumbai) by Dadoba Pandurang and others as a secret society to promote monotheism and combat social evils such as caste discrimination.

- Statement 2: Prarthana Samaj was indeed started in Maharashtra. It aimed to reform Hindu religious thought and practice, advocating for social reforms like women's education and the abolition of caste distinction.

Given these explanations:

- Option 1 is incorrect because statement 1 is incorrect.

- Option 2 is correct because statement 2 is correct.

- Option 3 is incorrect as only one statement is correct.

- Option 4 is incorrect because statement 2 is accurate.
