The "bi" in the word "bicameral" refers to the number 2: a bicameral legislature features two legislative bodies (the correct answer is D).
A legislature with one body would be called "unicameral".
Most legislatures only have one or two bodies, so the other words are not often used (and especially 100 legislative bodies would not be feasible to maintain).
Shamus Khan is a renowned sociologist with research interests on inequality and elites. He comes from an economically privileged immigrant family and attended St. Paul's school in Concord, New hampshire, where he graduated in 1996. Since he had a comfortable background and studied at that same institution, he was already familiar with the setting he would encounter during his reasearch in St. Paul's, which is stated in his book "Privilege
: The Making of an Adolescent Elite at St. Paul's School".
