Correct answer: (a) Vajasaneyi
Explanation
- A
Vajasaneyi
(a) Vajasaneyi. Shukla Yajurveda survives as the Vajasaneyi Samhita in Madhyandina and Kanva recensions, linked to Yajnavalkya. That stored name is the official key. White Yajurveda keeps mantra and brahmana layers apart.
- B
Maitrayani
(b) Maitrayani. Maitrayani is a Krishna Yajurveda samhita, mixed with brahmana prose, not Shukla.
- C
Taittiriya
(c) Taittiriya. Taittiriya Samhita is the principal Krishna Yajurveda recension of the Taittiriyas, not Shukla.
- D
Kathak
(d) Kathak. Kathaka (Kathak) is another Krishna Yajurveda school, alongside Kapisthala, not Vajasaneyi.
Summary. Official key is (a) Vajasaneyi. Only Vajasaneyi is the Shukla Yajurveda samhita among the four names. Maitrayani, Taittiriya and Kathaka belong to Krishna Yajurveda. Neighbouring labels are Madhyandina, Kanva and Yajnavalkya. Do not treat Kathak dance as this Vedic school.
