Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.787% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CCN1C(=O)N[C@H](c2ccc(Br)cc2)C(C(=O)OC)=C1C
b. N/C(=N\OC(=O)C1CCCCC1)c1cccnc1
c. COc1ccc(N2CC(C(=O)Nc3ccc(S(=O)(=O)Nc4nccs4)cc3)CC2=O)cc1
d. CCOCCn1c(COc2ccccc2)nc2ccccc21
Answer: a. CCN1C(=O)N[C@H](c2ccc(Br)cc2)C(C(=O)OC)=C1C
