Explanation
There was nothing so very remarkable in that; nor did Alice think it so very much unnatural to hear the Rabbit say to itself, “Oh dear! Oh dear! I shall be late!”; but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge.
Choice B is the best answer. The text discusses Alice’s encounter with a rabbit wearing a waistcoat. The text makes it clear that she finds nothing unusual about the talking Rabbit; however, it is only when it takes a watch out of its waistcoat pocket that she notices the Rabbit’s unusual aspects and burns with curiosity.
Choice A: The text makes it clear that Alice does not find anything unnatural when she hears the Rabbit speak.
Choice C: The text does not portray Alice as being in any way cautious about the Rabbit.
Choice D: Since the text explicitly states that Alice is burning with curiosity and runs after the Rabbit, it would not be correct to say that she is not bothered at all.

Notice the difference in Alice's attitude before and after the rabbit takes out the watch.
