Sandhi Combination of सत् + जनः

The question asks to find the correct sandhi (combination) of the Sanskrit words $सत्$ (sat) and $जनः$ (janaḥ).

Applicable Sandhi Rule

This problem requires applying the rules of हल सन्धि (consonant sandhi) in Sanskrit grammar.

Specifically, the rule concerning the change of the first consonant (प्रथम वर्ण-विकार) applies here.

The rule states that if the consonant $त्$ (t) is followed by the consonant $ज्$ (j), the $त्$ changes into $ज्$ (j).

This rule can be expressed as: $त् + ज् \rightarrow ज्$

Combining the Words

Let's apply this rule step-by-step:

• Given words: $सत्$ + $जनः$
• Identify the relevant consonants: The last consonant of the first word is $त्$ and the first consonant of the second word is $ज्$.
• Apply the rule: The $त्$ changes to $ज्$.
• The combination becomes: $सज्$ + $जनः$
• The final sandhi form is: $सज्जनः$

Therefore, the correct sandhi form of $सत् + जनः$ is $सज्जनः$.

Correct Option: D ($सज्जनः$)
