Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -4.189\% 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, or c without using any other words.
Options:
a) Cc1cc2c(c(=O)o1)C(C13C=CC(CC1)C3)C(C#N)=C(N)O2
b) Cc1cccc(C(=O)NCC(c2ccc(F)cc2)N2CCOCC2)c1
c) CCNC(=O)NC(=O)C(C)OC(=O)C1CCN(S(=O)(=O)c2ccc(C)c(C)c2)CC1
Answer: a. Cc1cc2c(c(=O)o1)C(C13C=CC(CC1)C3)C(C#N)=C(N)O2
