Answer:
C. "La fecha" should be changed to "el fecha."
Explanation:
Está means which and that would be "Which is today's date."
Cómo means how and that would be "How is today's date."
La fecha and el fecha both mean the same thing, "What is today's date."
Based off of this, I think C would be the best option.
Spanish is not my first language, please make note I am just trying to help :)
