Select the correct answer from the code given below:

Correct option is B

(i) Mahisasaka: The search results consistently identify the Mahisasaka as a school of early Buddhism, and a sub-sect of the Sthavira branch. It is not a Jain sect.

(ii) Kurchaka: The search results mention Kurchaka as a sub-sect of Jainism. Specifically, it's mentioned alongside Yapaniya and Nirgrantha (a name for Digambaras) in a grant by a Kadamba king, identifying it as a Jain sect.

(iii) Vatsiputriya: The search results define Vatsiputriya as a school of early Buddhism. It was a branch of the Sthavira school and known for its philosophy. It is not a Jain sect.
