If the instructor says something that you don't understand, which is the BEST action to take to gain clarification?

A) use your phone to search the Internet during class
B) ask another student after class
C) look it up in your textbook
D) raise your hand and ask for clarification

Raising your hand and asking for clarification directly from the instructor is the most immediate and effective way to address confusion or misunderstandings about the material being taught. This approach ensures that any misconceptions are corrected in real-time, benefiting not only the individual student but potentially others in the class who may have the same question or confusion.
