Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.239\% hERG inhibition at 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(Oc1ccc(Cl)c2ccccc12)N1CCCCC1
b) Cn1c(SCC2CCCCC2)nnc1-c1ccncc1
c) CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)COC(=O)c1cc2ccccc2cc1O
d) CCC(C(=O)NC1CCCC1)N(Cc1ccccc1Cl)C(=O)c1snc(C(N)=O)c1N
Answer: a. O=C(Oc1ccc(Cl)c2ccccc12)N1CCCCC1
