visa for inlaws

[remyajayce]

i am sponsering visa for my in-laws. In affidavit I have mentioned as I am inviting my "in-laws". While filling ds160, at couple of places(like "person/entity paying for trip) I have to provide my name adn address details. also they are asking for "relation ship". The drop down menu has three options that I feel applicable to me

1. Other
2. Child
3. Other relative

but it is not letting me to mention anywhere that I am son-in-law. If I choose option "child" would that be fine?

Other relative.

You are not their child.
