Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -24.337\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(C1CCCN(S(=O)(=O)c2ccc(Br)s2)C1)N1CCN(c2ccccc2)CC1
b O=C(c1ccco1)N1CCN(C(c2cccs2)c2sc3ncnn3c2O)CC1
c O=C(c1ccc(C(=O)N2CCN(c3ccccc3F)CC2)nc1)N1CCN(c2ccccc2F)CC1
d Nc1ccc(C(=O)[O-])c(O)c1.[Na+]
Answer: a. O=C(C1CCCN(S(=O)(=O)c2ccc(Br)s2)C1)N1CCN(c2ccccc2)CC1
