Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.300\% 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.) CCOc1ccccc1NC(=O)c1csc(C)c1C
b.) COc1ccc(C2CC(c3ccc(Br)cc3)=NN2C(=O)c2cccnc2)cc1
c.) COC(=O)/C=C/c1oc2ccccc2c1C
d.) O=C(CN1CC=C(c2ccccc2)CC1)Nc1c(Cl)cccc1Cl
Answer: d. O=C(CN1CC=C(c2ccccc2)CC1)Nc1c(Cl)cccc1Cl
