Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.443\% 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.) Cn1c(-c2ccccc2)cnc1NCc1cc(Cl)ccc1O
b.) O=C(Nc1ccccc1Oc1ccccc1)C1CCCC1
c.) COC(=O)c1ccc(NC(=S)N2CCN(C)CC2)cc1
d.) Cc1ccc(CSCCNC(=O)c2ccccc2)cc1
Answer: b. O=C(Nc1ccccc1Oc1ccccc1)C1CCCC1
