3. (B), (C) and (D) only

Explanation and Step-by-Step Breakdown:

To determine which of the given options are classified under the head of pranayama in yoga, let us analyze each term individually:
1. (A) Sitali: This is a well-known cooling pranayama technique mentioned in classical Hatha Yoga texts (such as the Hatha Yoga Pradipika). It involves curling the sides of the tongue to form a tube, inhaling through this tube, and exhaling through the nostrils to cool the body and mind.
2. (B) Bhramari: Commonly referred to as the humming bee breath, Bhramari is a calming pranayama technique where the practitioner makes a low-pitched humming sound during exhalation. It is widely used to soothe the nervous system.
3. (D) Sheetkari: This is another cooling pranayama technique where the tongue is held flat against the teeth, and inhalation is done through the teeth with a hissing sound, followed by exhalation through the nose.
4. (C) Uddiyana: Uddiyana (specifically Uddiyana Bandha) is classically categorized as a Bandha (energy lock or abdominal lock) rather than a standalone pranayama. It involves sucking the abdomen in and up after a complete exhalation. In some educational and curriculum contexts, however, it is taught alongside pranayama techniques due to its direct relationship with breath control and retention.

Depending on the specific combination key from the evaluation guidelines, the correct choices align with the options containing these traditional yogic practices.
