The correct answer is B.

Explanation: The underlined sound in "noise" is the "oi" sound, which is pronounced as /ɔɪ/.

- B. coin contains the same /ɔɪ/ sound as in "noise."

Other options:
- A. nose: Contains the /oʊ/ sound, which is different from the /ɔɪ/ sound.
- C. tortoise: Contains the /ɔɪ/ sound, but the vowel sound in "noise" is slightly different.
- D. loud: Contains the /aʊ/ sound, which is different from the /ɔɪ/ sound.
- E. time: Contains the /aɪ/ sound, which is different from the /ɔɪ/ sound.

Thus, "coin" is the option that contains the sound similar to the one in "noise."
