The statement that is NOT correct about Gandhi's speech at the opening of the Banaras Hindu University in February 1916 is:

(3) Gandhi said that the lawyers, doctors, and rich landlords are going to secure India's salvation.

In his speech at the opening of the Banaras Hindu University, Gandhi expressed concerns about the lack of representation of the millions of poor Indians and emphasized the importance of farmers in India's salvation. He also charged the Indian elite with a lack of concern for the laboring poor. 

The idea that lawyers, doctors, and rich landlords would secure India's salvation is not consistent with Gandhi's message in this context.. Gandhi believed in the empowerment of the masses and focused on their role in India's freedom struggle.

So,the correct option is [3].
