Read the following passage carefully and answer the question given below:

By the first century AD, many nomadic tribes had entered India through the mountain-passes in the north west. In the course of time, they were all Indianised. Kanishka, the chief of one of these tribes, built up an empire with Peshawar as the capital. Like Asoka, Kanishka came under the influence of Buddhism and was converted by a celebrated Buddhist scholar Asvaghosha. Kanishka appears to have tried to emulate Asoka. He strenuously worked for the spread of the Buddhist faith. He convened a Buddhist council to discuss grave religious problems. At the time, a big schism had arisen and the Buddhists were divided into two sects-the Hinayana and Mahayana. Of the two, the Mahayana became more popular. The Hinayanists believed in the traditional intellectual doctrine whereas the Mahayanists adopted new interpretations. The Mahayanists started worshipping Buddha as the living saviour and their ritualism had a strong appeal to the ordinary people. Nagarjuna, a great scholar in the court of Kanishka, formulated and propagated the Mahayana ideas. The differences between the two sects were largely reconciled in this council. Charaka, the most celebrated medical scientist of ancient India, is believed to have been Kanishka's court-physician. The Kushan empire built by Kanishka was dissolved by the third century AD.

Which of the following statements is NOT true about Kanishka?

(A) He was the chief of a nomadic tribe
(B) He was converted to Buddhism by Nagarjuna
(C) Charak was Kanishka's count physician
(D) He was the founder of the Kushan empire

Choose the correct answer from the options given below:

(B) Only

The correct answer is Option (1) → (B) Only

"He was converted to Buddhism by Nagarjuna" as NOT true about Kanishka is that the passage clearly states that Kanishka was converted to Buddhism by a celebrated Buddhist scholar named Asvaghosha. Nagarjuna is mentioned in the passage as a great scholar in the court of Kanishka who formulated and propagated the Mahayana ideas, but he was not responsible for Kanishka's conversion to Buddhism.
