Who among the following was a ruler of Shunga dynasty?

Pushyamitra

The correct answer is Option 2- Pushyamitra

Pushyamitra was a ruler of the Shunga dynasty. The other options are incorrect:

• Porus was a king of Paurava kingdom, who was defeated by Alexander the Great in 326 BCE.
• Bindusara was the second emperor of the Maurya Empire and the son of Chandragupta Maurya.
• Ashoka was the third emperor of the Maurya Empire and the son of Bindusara.

Pushyamitra was the founder of the Shunga dynasty, which ruled over much of northern India from around 185 to 73 BCE. He was a general in the Maurya army and seized power after assassinating the last Maurya emperor, Brihadratha.

Pushyamitra was a controversial figure. He is said to have been a persecutor of Buddhists, but he also patronized Brahmanism and built many temples and monasteries. He was a skilled military leader and successfully defended the Shunga Empire from foreign invaders.
