Final answer:
The correct answer to the sentence 'Someone used terminal B to smuggle raw ingredients' is 'B. Conceal'. Smuggling involves the act of hiding, which is the meaning of 'conceal'.
Step-by-step explanation:
The word 'smuggle' used in the context of the sentence refers to the act of concealing something to move it illegally into or out of a location. So, the correct answer to 'Someone used terminal B to smuggle raw ingredients' would be 'B. Conceal' since smuggling involves the act of hiding something to avoid it being found or taken by customs or authorities. Other options such as disclose, declare, and expose are antonyms to 'smuggle' because they all involve revealing or making something known, which is the opposite of what smuggling entails.
