Problem statement: Answer the multiple choice question.
Query: Which drug has a 8.406\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCOCCCNC(=O)C1CCN(c2cc(C)nc3c(-c4ccc(OC)c(OC)c4)c(C)nn23)CC1
(b) C=CCn1c(=O)/c(=C2/Sc3cc(OC)ccc3N2C)s/c1=C1\C(=O)N(CC)C(=S)N1C
Answer: b. C=CCn1c(=O)/c(=C2/Sc3cc(OC)ccc3N2C)s/c1=C1\C(=O)N(CC)C(=S)N1C
