1. My child has better hygiene than that of my
sister.
2. My child has better hygiene than my sister.

which one is correct?

1 is correct . Since we are comparing hygiene . Statement 2 compares hygiene to "my sister".

thanks for the reply abhi.
but the explaination to this question is below and according to this explaination.
But still i am not convinced:

This question is about subject-verb agreement and pronouns.
The pronoun "those" seems to be referring back to "child."
Since "child" is singular, this is incorrect. Additionally, since
"neither" is singular ("of her boys" is merely a prepositional
phrase), the verb "seem" and the pronoun "their" are both
incorrect.

Correct: My child has better hygiene than my sister's children;
