Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 14.061\% 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, d, or e without using any additional words.
Options:
a: COc1cccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)c1
b: C=C(C)CCC1(C)NC(=O)N(c2ccccc2)N1
c: CC1CCCCC1NC(=O)CN1CCC(NC(=O)c2cccc(F)c2)CC1
d: Cc1cccc(NCc2ccccc2O)c1C
e: CCOc1ccc(Nc2cc(C)nc3c(C)cccc23)cc1
Answer: a. COc1cccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)c1
