c. high-pitched sounds

Explanation:

According to my research on Movie Audio, I can say that based on the information provided within the question this sense of tension is usually achieved by high-pitch sounds. This technique is mostly used in suspense sequences, usually just before and during the climax. Like in movies like Friday the 13th when the serial killer is about to kill someone.
