According to Sushruta, the phrase "मातु: कृषिं न पुरूषति मन्दं स्नपन्ते च" is associated with the condition of Vatabhi panna garbha. This phrase suggests a condition where the fetus, influenced by the Vata dosha, does not develop properly and is weak or slow to grow, which aligns with the characteristics of Vatabhi panna garbha.
- Leena garbha refers to a condition of a fetus in which it is weakened or debilitated, but it is not directly associated with the phrase mentioned in the question.
- Nagodara is related to a swollen or distended abdomen, not directly linked to the phrase.
- Upavishtaka garbha refers to a fetus in the seated position, but this is not the context for the phrase.
Thus, the correct answer is (3) Vatabhi panna garbha.
