Answer:
A behavioral reproductive isolating mechanism.
Explanation:
Isolating mechanisms may be defined as the mechanism that do not allow the different species to mate with each other. Two main isolating mechanisms are prezygotic isolating mechanism and a postzygotic isolating mechanism.
The behavioral isolating mechanism is a type of pre zygotic reproductive isolating mechanism in which the species are unable to meet with each other due to the differences in their courtship behavior that includes different sounds and color. The cricket species is unable to meet with each other due to difference in their courtship behavior.
Thus, the correct answer is option (A).

The efficiency indicates the manner in which the inputs are used by the system. Being efficient means the system uses inputs in a `right' way. If the input-output ratio is adverse, we say that the system is inefficient though it produces the desired output.
