What is its name
Duolingo says "उसका नाम क्या हैं but I'm sure it should be "इसका नाम क्या हैं " Please comment.
Oliver192922, this is the correct answer. इसका is a form of यह (this/he/she/it) and is used for someone or something who is close by (either physically or figuratively). Similarly, उसका is a form of वह (that/he/she/it) and is used for someone or something who is far away (physically or figuratively). The choice between the two is very similar to how you choose between 'this' and 'that' in English.
