Answer: a. too much acetylcholine staying in the neuromuscular junction for too long
Explanation:
Sarin is a gaseous organophosphate. This gas is used for chemical warfare. This affects the nervous system of the body. The gas if inhaled can cause death within minutes.
Acetylcholine is a neurotransmitter molecule. It is released from the pre-synaptic neurons that binds to the acetylcholine receptors.
The gas sarin will target the enzyme acetylcholinesterase present in the neuromuscular junction of the body where the nerves actually meet the muscles. The enzyme degrades nerve signaling molecule acetylcholine. Thus when the sarin degrades the enzyme the levels of acetylcholine will rise up in the blood. The acetylcholine remain in the neuromuscular junction. The acetylcholine will stimulate the nerve cell receptors. Excess of acetylcholine will cause excessive twitching and may lead to paralysis.
When conducting a causation study, it is important to know that changes in the dependent variable result in changes in the independent variable.
<h3>What is Causation study?</h3>
This is the study which occurs when one event causes the other to occur in a study.
In most studies, the changes in the dependent variable results in the changes in the independent variable thereby causing certain events to occur.

Based on subpart B of the IBD guidelines the research described would be permitted.
The Institution Review Board or IBD is the entity in charge of evaluating possible research studies and determine if these are ethical.
In the case of fetuses and pregnant women, the guidelines are established in the subpart B, and the most important points include:
- Research studies are ethical if the possible risks have been studied and are well known
- Research studies are ethical if they provide a benefit to the fetus and/or woman
- Research studies are ethical if there is no benefit either for the fetus or the woman but the risk is minimal
Based on this, the research described would be permitted because even if there is a low risk for the fetus, the study has the potential to provide benefits for both the fetus and the mother, which makes the risk to be ethical and acceptable.
