When inference is based not on Causation but on Uniformity of co-existence as in the case of inferring cloven hoofs of an animal by it’s horns; it is called

The correct option is Samanyatodrsta.

Step-by-Step Explanation:

In Classical Indian Philosophy (specifically the Nyāya school), Anumāna (inference) is classified into three types based on the nature of the relation (vyāpti) between the reason (hetu) and the consequence (sādhya):

1. Pūrvavat Anumāna: This is an inference of an unperceived effect from a perceived cause. For example, inferring imminent rain by looking at dark, heavy clouds in the sky.
2. Śeṣavat Anumāna: This is an inference of an unperceived cause from a perceived effect. For example, inferring that it rained in the past (cause) by observing a muddy, overflowing river (effect).
3. Sāmānyatodṛṣṭa Anumāna: This type of inference is not based on a causal relation (cause-effect) but rather on the uniformity of co-existence (non-causal association). It is an inference based on general observation. When two characteristics are repeatedly observed together without one causing the other, the presence of one indicates the presence of the other.

Applying the Concepts:

In the given question, we are inferring that an animal has cloven hoofs because it has horns. Having horns does not cause cloven hoofs, nor do cloven hoofs cause horns. However, they uniformly co-exist in certain classes of animals. Because this inference is based purely on a non-causal uniformity of co-existence, it is called Sāmānyatodṛṣṭa.
The option Pakṣadharmatā refers to the presence of the middle term (hetu) in the minor term (pakṣa), which is a step in the process of inference rather than a classification based on causal relations.
