Option b is the correct answer. The Sarnath Pillar, known as the Lion Capital of Ashoka, was built by the Mauryan emperor Ashoka around 250 BCE. It features four life-sized lions back-to-back on an abacus, symbolizing Ashoka's association with Buddhism. The pillar commemorates the site of Gautama Buddha's first sermon. It stands 2.1 meters tall, crafted from a single block of polished sandstone. This iconic pillar is on display near its original location in Sarnath, representing both Buddhist and secular symbolism. The Lion Capital also inspired India's national flag emblem and state emblem.
