The correct answer is option (B):
different and superior than yours
The correct answer is "different from and superior to yours". Here's why:
The word "different" is correctly followed by the preposition "from" when comparing things. You say something is "different *from* something else."
The word "superior" is correctly followed by the preposition "to" when comparing things. You say something is "superior *to* something else."
Let's look at why the other options are incorrect:
* "different and superior than yours" is incorrect because "superior" takes "to", not "than."
* "different from and superior than yours" is incorrect because "superior" takes "to", not "than."
* "different and superior to yours" is incorrect because "different" takes "from", not just being used by itself.
