Task: Answer the multiple-choice question.
Question: Which drug exhibits a -5.111\% 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 O=C(O)CCN1C(=O)c2ccccc2C1=O
b O=S(=O)(NCCc1csc(-c2ccc(C(F)(F)F)cc2)n1)c1ccc2c(c1)OCCO2
c COc1ccc(S(=O)(=O)N2CCOCC2)cc1NC(=O)Cc1coc2cc(C)c(C)cc12
d CSc1nc(N)nc(SCC(=O)Nc2ccc(Cl)cc2)c1C#N
Answer: d. CSc1nc(N)nc(SCC(=O)Nc2ccc(Cl)cc2)c1C#N
