Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.020\% 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 COc1ccc(N2C(=O)CC(S/C(N)=N/N=C/c3ccnc4ccccc34)C2=O)cc1
b COc1ccc(CCNC(=O)CCCN2C(=O)c3ccccc3C2=O)cc1OC
c Cc1ccc(S(=O)(=O)N2CCN(C(=O)c3ccc(Cl)nc3)CC2)cc1
d CCOc1c(Cl)cc(CNc2ccc(S(N)(=O)=O)cc2)cc1OC
Answer: d. CCOc1c(Cl)cc(CNc2ccc(S(N)(=O)=O)cc2)cc1OC
