Dash:
The main function of the dash, like parentheses, is to enclose emphasized information within a sentence. Dashes are more forceful and should be used sparingly, since they high-light the ideas and items they enclose.
Use dashes to indicate hesitation, or a sudden break in thought or sentence structure, or to set off appositives and other explantory or parenthetical elments. The dash adds emphasis to any part of a sentence that can be separated from the rest of the sentence.
Example: The skydriver--in spite of his broken leg--set a new record for endurance.
Some specific uses of the dash follow:
1. To interrupt continuity of prose
Example: "I really can't tolerate--Well, never mind."
2. To emphasize appositives
Example: The items she had asked for in the new car--tape deck,mileage computer, stick shift--were all included.
3. To set off phrases or clauses containing commas.
When a modifier itself contains commas, dashs can make its boundaries clear.
Example: General Motors--which has manufactured tanks, cannons, and mobile cranes--has always been far more than an automobile assembler.
4. To set off parenthetical elements
Example: The child was sitting--actually sprawling--at his desk.
According to the definition above, I support "B",because "dash" here expresses emphasis,对应 only.
