Hello!
We can cancel out C because most people don't crash during the day. That leaves us with 2 reasonable answer choices. We can cancel out A because yes, it is a long trip, however, when you are closer to home you think you are safe and start falling asleep or even driving more recklessly. So that leaves you with your best answer choice.
I am, yours most sincerely,

No... Down Syndrome is a chromosome deficiency that happens during conception when a spem and egg fertilize. Sometimes the X and Y Chromosomes don't add up correctly and can (sadly) cause this deficiency. Water in the mother's lungs can cause pneumonia which can potentially harm the fetus due to lack of oxygen. But this cannot cause down Syndrome. Water in the baby's lungs will also not cause Down Syndrome.
