Task: Answer the multiple-choice question.
Question: Which compound exhibits a 3.391\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) CCC(CC)C1C(C#N)=C(N)Oc2n[nH]c(-c3ccccc3)c21
b.) Cl.N=C(N)SCc1ccccn1
c.) CC(C)(C)c1cc[n+](/C(C(=S)NC2CC2)=C(/[O-])c2ccc(Cl)s2)cc1
d.) O=C(c1ccc(Cl)cc1)N1CCN(S(=O)(=O)/C=C/c2ccccc2)CC1
Answer: b. Cl.N=C(N)SCc1ccccn1
