Step 1: Understanding the Concept:
The question requires the identification of ancient Indian texts belonging to the Buddhist tradition from a given list.
Step 2: Detailed Explanation:
Analysis of each text is as follows:
(A) Sutrakṛtāṅga: This text is part of the Śvetāmbara Jain canonical texts (one of the twelve Aṅgas). It outlines Jain doctrines and criticizes contemporary philosophical schools. Thus, it is a Jain text.
(B) Dhammapada: This is a prominent text from the Pāli Canon of Theravāda Buddhism, featuring the Buddha's sayings in verse. It belongs to the Khuddaka Nikāya and is a Buddhist text.
(C) Dīghanikāya: Meaning "The Collection of Long Discourses," this is the initial Nikāya within the Sutta Piṭaka of the Pāli Canon. It comprises significant sermons by the Buddha and is a Buddhist text.
(D) Sutta Nipāta: This significant text is also part of the Khuddaka Nikāya of the Pāli Canon. It is a compilation of discourses (suttas) and is recognized as an early Buddhist scripture. Thus, it is a Buddhist text.
Step 3: Final Answer:
Following the analysis, Dhammapada (B), Dīghanikāya (C), and Sutta Nipāta (D) are confirmed as Buddhist texts. Sutrakṛtāṅga (A) is identified as a Jain text. Therefore, the correct option comprises (B), (C), and (D) exclusively.
