the fundamental idea behind natural selection is that, within a particular environment, a genetically influenced trait tends to be more successful and thus able to survive and be passed on. Environmental psychologists examine the ________ that led to survival, and which then led to further reproduction for survival. It doesn't matter to environmental psychologists whether those behavioral tendencies are adaptive in today's environment.

a) behavioral tendencies
b) innate characteristics
c) heritability
d) psychological traits

I am kind of confused but I chose D. Am I right?

I don't think so.

Based on the information you provided, the answer to the question seems to be a) behavioral tendencies. Natural selection is a process where traits that enhance an organism's chance of survival and reproduction are more likely to be passed on to future generations. Environmental psychologists specifically focus on the behaviors that lead to survival and reproduction, regardless of whether those behaviors are adaptive in today's environment. Psychological traits (option d) may be influenced by natural selection, but the question is specifically asking about the behaviors that led to survival.
