(7) My heart started to beat faster. (8) Finally, I reached the top of the stairs. (9) I slowly opened the bedroom door.

Which of these BEST replaces sentence 7 with descriptive detail?

A) My heart began to race.

B) My heartbeat increased.

C) My heart seemed to beat out of my chest.

D) My heart started to beat much more rapidly.

the right option is C.

Descriptive details resort to the recreation of sensorial experiences in such a way that the reader can feel as if they were into the scene.

Hence, sentence 7 is best replaced by option C "my heart seemed to beat out of my chest" because it is the one that describes a physical reaction motivated by a given situation.

the second option.is correct
