What is the correct Sandhi-Viched (decomposition) of the word 'अन्तर्निहित'?

The word 'अन्तर्निहित' is formed using Visarga Sandhi rules. According to the rule, when a visarga ($\text{:}$) is preceded by any vowel other than 'अ' or 'आ', and followed by a voiced consonant, vowel, or third/fourth/fifth letter of a consonant group, the visarga converts into 'र्' ($\text{r}$).
$$\text{अन्त:}+\text{निहित}=\text{अन्तर्निहित}$$
