Answer 3

The correct answer is c) but.

Explanation: The conjunction "but" is used to show contrast or opposition between two ideas or actions. In this case, the sentence suggests that the speaker has opened the door, but there is no information about whether or not they have opened the window. The conjunction "but" is appropriate because it introduces a contrasting action or situation.
