Problem statement: Answer the multiple-choice question.
Query: Which drug has a -5.521\% 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) Cc1ncc(CNC(=O)N(CCCl)N=O)c(N)n1.Cl
(b) COCCNC(=O)COC(=O)/C=C/c1c(C)nn(Cc2ccc(Cl)cc2Cl)c1Cl
(c) CCCN1CCN(CCCNC(=O)c2ccc3c(Cl)c4c(nc3c2)CCCC4)CC1
(d) O=C(CNc1ccc(Cl)cc1)c1ccc(Br)cc1
Answer: b. COCCNC(=O)COC(=O)/C=C/c1c(C)nn(Cc2ccc(Cl)cc2Cl)c1Cl
