What does this Chinese character mean in English?

All three answers are not wrong. It's like defining mad as crazy or angry. Both are correct, right?

Anyway, if you take the rest of the picture into context, then the second answer would be ideal. Incidentally, 志 is also a Japanese word with the same meaning.

By the way, that is one awful depiction of 志 in the picture. Most teachers would mark it as wrong if you were to write it like that. Definitely not a Japanese or Chinese who designed that.

English utilising alphabet to combnaition a word then provide its means, chinese language utilising character to combnaition a word, so "?" is possitive character in chinese language, like "??"= hero, "??"=smart;astonishing, "????"=plenty flower falling,"??"=English, "??"=handsome, "??"=holy spirit, there nonetheless a lot words like those, you may choose for certainly one of this to describe this character.

志 = zhi4 = a mark or a sign

it's 志，which means ambition

It means "will" or "purpose".
