Who was the author of "Unhappy India"?

The correct answer is Option 4 - Lala Lajpat Rai

The author of "Unhappy India" is Lala Lajpat Rai.

Lala Lajpat Rai was a prominent Indian independence activist, Arya Samaj leader, and author. He was known as the "Punjab Kesari" (Lion of Punjab) for his fierce opposition to British rule. He was also a prolific writer, and his book "Unhappy India" was a response to the negative portrayal of India by American journalist Katherine Mayo in her book "Mother India".

In "Unhappy India", Rai challenged Mayo's claims and presented a more balanced and nuanced view of Indian society. He also criticized British colonial rule for its negative impact on India's economy, culture, and social development.

Rai's book was a powerful indictment of British colonialism, and it helped to inspire a new generation of Indian freedom fighters. It is still considered an important work of Indian literature today.
