Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.831\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) O=C(NCc1ccc(F)cc1)C1Cc2ccccc2CN1C(=O)c1ccco1
b) Br.CCOc1ccc(S(=O)(=O)NN2Cc3ccccc3C2=N)cc1
c) Cc1c(C(=O)N2CCCCC2)c(S(=O)(=O)NCc2ccc(N(C)C)cc2)c(C)n1C
d) Cn1c(N)c(C(=O)CSc2n[nH]c(-c3ccccc3)n2)c(=O)n(C)c1=O
e) CCN(CC(=O)NCc1cccnc1)S(=O)(=O)c1ccc(OC)cc1
Answer: d. Cn1c(N)c(C(=O)CSc2n[nH]c(-c3ccccc3)n2)c(=O)n(C)c1=O
