Task: Answer the multiple choice question.
Question: Which drug has a 9.996\% 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 additional words.
Options:
a) CCC(C)NC(=O)CSc1nc2ccccc2c(=O)n1Cc1ccc(OC)cc1
b) CC(=O)c1ccc(O)c(CC=C(C)C)c1O
c) C=CCn1c(N2CCCC2)nc2c1c(=O)n(C)c(=O)n2C
d) C=CCc1c(C)[nH]c2c(OC)cccc2c1=S
Answer: c. C=CCn1c(N2CCCC2)nc2c1c(=O)n(C)c(=O)n2C
