Answer: Option B: constructive interference
Explanation: When two waves find in a point in space, and the resultant wave is a bigger wave, this means that there has been a "constructive interference", where constructive means that the waves are "constructing" with each other, and interference is the phenomena that happen when two waves meet. Â
The other case, if after the two waves meet, the result is a smaller wave (or not wave at all) its called "Destructive interference"
