Task: Answer the multiple-choice question.
Question: Which drug has a 0.026% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a Cc1cccc(-n2c(O)cnc2Nc2nc(C)cc(C)n2)c1
b Cc1cc(C(=O)Nc2ccccc2N2CCOCC2)c(C)o1
c NC(=O)CSc1nccn1Cc1ccc(Cl)cc1
d CCCCC(=O)N/N=C(\C)CC(=O)Nc1ccccc1Br
Answer: d. CCCCC(=O)N/N=C(\C)CC(=O)Nc1ccccc1Br
