Choose the appropriate option to fill in the blank in the given sentence:

______ you please show me the way to station?

(A) could
(B) will
(C) should
(D) can

Choose the correct answer from the options given below:

(A) Only

The correct answer is Option (4) → (A) Only

The sentence is a polite request. In English, when making polite requests, "could you" is preferred over "can you" or "will you."

• "Could you please show me the way to the station?" — This is the most polite and grammatically correct form.

• "Can you" and "will you" are grammatically possible but less polite or too direct.

• "Should you" is incorrect in this context.

Therefore, "could" is the best and most appropriate choice.
