Which of the following sequences correctly represents the chronological order of the following Sanskrit works, from earliest to latest?

निम्नलिखित में से कौन सा क्रम इन संस्कृत कृतियों के सबसे पहले से नवीनतम तक के सही कालानुक्रमिक क्रम का प्रतिनिधित्व करता है?

Panini's Ashtadhyayi is generally dated to about the 5th-4th century BCE. The Tripitaka (the Pali canon) was compiled over several centuries after the Buddha's death and took its final form by about the 1st century BCE, when it was written down, so it is placed after the Ashtadhyayi in this question. Ashvaghosha's Buddhacharita belongs to about the 1st-2nd century CE and Hemachandra's Parishishtaparvan to the 12th century CE. Hence the order is Ashtadhyayi, Tripitaka, Buddhacharita, Parishishtaparvan.
