Step 1: Meaning of Pañcāṅga.
Pañcāṅga literally means “five limbs.” It refers to the five basic elements used for determining time in Jyotiṣa Śāstra.

1. Tithi (lunar day).
2. Vāra (weekday).
3. Nakṣatra (constellation).
4. Yoga (planetary combination).
5. Karaṇa (half of a Tithi).
Step 3: Checking the options.
- Tithiḥ: Included in Pañcāṅga.
- Vāraḥ: Included in Pañcāṅga.
- Nakṣatram: Included in Pañcāṅga.
- Rāśiḥ: Zodiac sign, not part of Pañcāṅga.
