Would you pass mesalt, please any            B.a             C.some

The correct answer to the question "Would you pass mesalt, please?" is C. some.

In English, the word "some" is used in requests and offers when the quantity is not specified or when it is not necessary to quantify exactly how much is being referred to. The phrase "Would you pass me some salt, please?" uses "some" to imply a certain amount of salt, acknowledging that it is normally not appropriate to specify an exact amount in such a polite request.

The option "any" (A) typically suggests a more negative or indefinite context, often used in questions or negative statements, as in "Do you have any salt?" Therefore, it does not fit well in this polite request format.

The option "a" (B) implies a singular countable noun, which does not apply to "salt" in this context since it is an uncountable noun when referring to a substance in general. Hence, "a salt" does not make sense.

Thus, the most appropriate word to complete the sentence is "some," leading to the polite request: "Would you pass me some salt, please?"
