The word, "can", "could", "will" and "would" are called modal auxiliaries which are helping verbs which are usually used along with the main verb in a sentence. The main verb in the given sentence is "like". The speaker is posing a question whether the listener would, in the future, like to buy jewellery or a dress. It expresses a choice of one action vs another in the future.
"Can" is a verb, which means: Be able to/ be permitted to. When used in a question, it is used to ask about someone's ability to do something. An example of its usage in future tense is: "Can you do this job without my help?". "Can you like" is grammatically incorrect as there is no question about the listener's ability to "like" something. Hence, option A is incorrect.
The word, "could" is used to describe something which is likely to happen. When used in a question, it is used to ask for permission/request someone. An example of its usage is: "Could you please let me know the answer?" In the given sentence, permission is not sought. Nor is a request made. Hence, option B is incorrect.
The word, "will" is used in a question to ask if a certain action is expected to happen in the future. An example of its usage is: "Will you help me"? Which means: Is there a certain possibility that you will help me. "Will you like" is grammatically incorrect. Hence, option C is incorrect.
The word, "would" used in a question to ask whether someone will do an action in the future or not. It expresses a choice. Hence, "would" is the most appropriate choice. Hence, option D is correct.
