Is the Indonesian correct ? "La" for "he" ? Not "dia" ? I've not seen "La" before.
It's "ia" starting with the letter that sounds like "eye". Duolingo should consider using a different font that makes a clearer distinction between capital I (eye) and lower case l (ell).
Dia is for he/she, but so is Ia. They are both used for humans, so yes the Indonesian is correct.
