With reference to the religious practices in India, the "Sthanakvasi" sect belongs to

1. A

   Buddhism

   (a) Buddhism. Buddhist schools include Theravada, Mahayana and Vajrayana; Sthanakvasi is not one of them. This option is not the key.

2. B

   Jainism

   (b) Jainism. Sthanakvasis are a Svetambara Jain sect that rejects idol worship and worships in sthanaks (halls) rather than temples. That is the Indian religious identification asked. This option is the official key.

3. C

   Vaishnavism

   (c) Vaishnavism. Vaishnava sampradayas centre on Vishnu/Krishna; Sthanakvasi is not among them. This option is not the key.

4. D

   Shaivism

   (d) Shaivism. Shaiva traditions worship Shiva; they do not include Sthanakvasi. This option is not the key.

Summary. Official key is (b) Jainism. Sthanakvasi is a non-idolatrous Svetambara Jain tradition, distinguished from Murtipujaka temple Jains and from the later Terapanth. It is not a Buddhist nikaya and not a Vaishnava or Shaiva sampradaya. The WRAP identification is therefore Jainism. That matches the stored letter (b).
