Task: Answer the multiple-choice question.
Query: Which compound has a 1.950\% 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) CCn1ncc(N(C)N)c(Cl)c1=O
(b) O=C(CSc1nccn1-c1ccccc1)c1ccc(Cl)cc1
(c) O=C(Cn1c(-c2ccc(Cl)cc2)noc1=O)N1CCN(c2ccccc2F)CC1
(d) O=S(=O)(c1cccc(C(F)(F)F)c1)N1CCN(c2ccccc2)CC1
Answer: b. O=C(CSc1nccn1-c1ccccc1)c1ccc(Cl)cc1
