If you want to use 'what' you have to say:

What name did you choose for the puppy?

hi all,

Isn't which limited between two.

and what is the correct answer?

best regards.

The correct answer, as indicated in the original post and when you click to display the answers in the test, is 'which'.
This is the only possible answer to the question as written, because the question MUST relate to a limited choice of names as otherwise the definite article would not be used before 'names' (and no, it doesn't have to be limited between two. It can be limited between other numbers in a group too.)
In message #2 in this thread Conchita points out that in order to use 'what' you cannot indicate a limited choice to begin with. Compare the two:
Which of the names did you choose? <-- there were a limited number of names available. You had to choose from a predefined set.
What name did you choose? <-- there is no limit to the names. You could have chosen anything.
