"What is the mode of transport that you like most?"

Translation: Apakah alat transportasi yang paling kamu suka?

[yipivan]

I thought it should be apa instead of apakah. Isn't "what" apa instead?

A kind answer by demoksaputra.

Apa and apakah are the same. Although, apakah is more formal than apa. The suffix –kah is used to turn regular question sentence into a more polite form.

I think apa instead of apakah is the most suitable. is it?

Please explain why this "Apakah alat transportasi yang kamu paling suka?" is not an acceptable answer?

[Rick392366]

This 'yang' clause is a passive structure (passive type 2).
In such a structure, the agent/actor ('kamu') and the verb ('suka') cannot be separated.

Here is more info about the passive type 1 & 2 :

Thank you for the explanation.

A follow up question if I may. Sticking with the same question and if I were to answer the question, which of the following answers is correct/acceptable?

1) “Saya paling suka sepeda motor” (the agent/actor and the verb are separated)

2) “Paling saya suka sepeda motor” (the agent/actor and verb are not separated)

3) “Yang paling saya suka sepeda motor” (the agent/actor and verb are not separated).

[Rick392366]

I would answer with sentence (1).
Sentences (2) and (3) use the word order of a passive type2 sentence, but there is need to use that here.
Sentence (3) is a 'yang' clause (passive type2), and it can be used like that if there is another phrase preceding this 'yang' clause.

Isn't "subordinate clause" the correct term rather than "passive structure"?
