Task: Answer the MCQ question.
Question: Which drug exhibits a -3.580\% 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 additional words.
Options:
a: O=C(c1ccco1)N1CCN(C(=S)Nc2ccc(Br)cc2Cl)CC1
b: Cc1ccc(-c2ccc(SCC(=O)Nc3cc(C)on3)nn2)cc1
c: O=C(Nc1cnccn1)Nc1ccc(Cl)cc1Cl
d: COc1cc(/C=C/C(=O)OCC(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)ccc1OCC#N
Answer: a. O=C(c1ccco1)N1CCN(C(=S)Nc2ccc(Br)cc2Cl)CC1
