16) Its quite obvious that B shows the largest temperature change as it is the smallest !
17) B .. heating the iron (or any metal) results in expansion .. this is easy to fit over the wooden spokes, as it is cooled it fits perfectly over the wood

i didnt get 16.....if temp increases it should expand and it should become larger

Least thermal capacity = large temperature change. the object with least thermal capacity will be of the one with least mass - B
Heating the iron circle will expand it, and thus it will be easier to put it on the wodden circle.
