Form classification is the classification of organisms based on their morphology, which does not necessarily reflect their biological relationships. Form classification, generally restricted to palaeontology, reflects uncertainty; the goal of science is to move "form taxa" to biological taxa whose affinity is known.
The answer would be bronchitis as it has to do the bronchial tubes
Hope this helps :)

Do you have any statements to go along with this question?
Answer:
E) sister chromatids separate during anaphase of meiosis I.
Explanation:
Chromosomes are composed of two chromatids which are joined together through centromere. Chromosomes get doubled its chromatids during its S phase of Interphase. Although chromosomes number remains the same as after S phase but number of chromatids becomes double.
For Example:
In humans 46 chromosomes are present before S phase and 46 chromosomes after S phase. only difference is that chromatids before S phase is 46 in number while after S phase it becomes double i.e becomes 92.
During Prophase 1 of Meiosis 1 these 46 chromosomes with 92 chromatids get arranged in manner that homologous chromosome pair comes close together and form 23 pairs.
During Metaphase 1: These 23 pairs get arranged in center and attached with spindle fiber present inside cells. Each spindle fiber attach to one member of the pair in a manner that 23 spindle fibers from one side of pole attached to one member of homologous chromosome pairs and 23 spindle fibers from other side of pole attached to other member of homologous chromosome pairs.
In Anaphase 1 of Meiosis 1 these spindle fibers get contracted and pulled attached chromosome along with them towards opposite poles. In this manner chromosome numbers in Meiosis become half as compared to the Mitosis
So Correct Answer of the question is
E. sister chromatids separate during anaphase of meiosis I.
