Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 15.273\% 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(NCCCCNC(=O)c1cccnc1Cl)c1cccnc1Cl
b. O=C(O)c1cc2n(n1)C(C(F)(F)F)CC(c1ccccc1)N2
c. Cc1cc(OC(C)C(=O)NCCCn2ccnc2)c2c(C)c(C)c(=O)oc2c1
d. Cn1c(=O)c2c(ncn2CC(=O)OCC(=O)c2ccc(Cl)cc2)n(C)c1=O
Answer: a. O=C(NCCCCNC(=O)c1cccnc1Cl)c1cccnc1Cl
