d. observational learning

a. classical conditioning

Explanation:

since Barbara liked cats until she had a bad experience, from there until now, the upsetting feeling is related with cats. In a classical conditioning there will be a stimulus, like the cat or the bitten of another animal associated with a response that could be conditional, like in this case that is the feeling as the consequence of the act of bitten.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m
