According to a 2005 report from the environmental protection agency, levels of what organochlorine pesticide are low or undetectable in the united states population, which reflects progress in the control of toxic chemicals

Dieldrin

Explanation:

Dieldrin is an example of organochloride compound which is derived from aldrin. When aldrin undergoes more chemical reaction, it creates the widely known compound called dieldrin which is the pesticide used to control insects.

Therefore, if we consider the 2005 report from the Environmental Protection Agency, the levels of dieldrin are low/undetectable in the US population, which shows the progress in the control of toxic chemicals in US.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
