Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -3.467\% 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) COCc1[nH]nc2c1C(c1ccccc1OC)C(C#N)=C(N)O2
b) O=C(Nc1ccc(Cl)cn1)c1ccc(-c2ccc(Cl)c(Cl)c2)o1
c) COc1cc(C2C(C#N)=C(N)Oc3cc(C)oc(=O)c32)ccc1OC(=O)N1CCOCC1
d) Cc1c(-n2c(SCC(=O)NC(C)C)nc3ccccc3c2=O)c(=O)n(-c2ccccc2)n1C
Answer: c. COc1cc(C2C(C#N)=C(N)Oc3cc(C)oc(=O)c32)ccc1OC(=O)N1CCOCC1
