Answer
Answer: b. Anxiety disorders are caused by a combination
of genetic and environmental influences.
Explanation:
Hypothesis: A statement which we are
going to test through experiment called hypothesis. It means
hypothesis is just an assumption and it has no proof. That’s why
hypothesis doesn’t build cause and effect relationship between
variables.
In the above case, Statements a,c and d didn’t build causal
relationship between variables. They just explaining the
situations. That’s why they are hypotheses. But statement b build
the causal relationship between Anxiety disorders and genetic,
environmental influences. That’s why statement b is not a
hypothesis because hypothesis never try to build causal
relationship between variables.
