Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.727\% 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 other words.
Options:
a. CNC[C@H](O)c1cccc(O)c1.Cl
b. COc1ccc(-n2cccc2/C=C2\C(=N)N3N=C(C(C)C)SC3=NC2=O)cc1
c. O=C(O)C1CCC(CNCc2ccccc2Cl)CC1
d. O=C(CCC1CCCC1)Nc1ccc(Br)cn1
Answer: a. CNC[C@H](O)c1cccc(O)c1.Cl
