Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.502\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CC1CC2=C(NC(=S)NC2c2ccccc2F)/C(=C/c2ccccc2F)C1
b) O=C(O)C(=O)O.c1ccc(-c2ccccc2OCCOCCN2CCOCC2)cc1
c) CCOc1nc(OCC)nc(N2CCC(C)CC2)n1
d) CC12C=CC3(O1)C(C(=O)N(c1cccnc1)C3C(=O)NC1CCCCC1)C2C(=O)Nc1ccccc1
Answer: a. CC1CC2=C(NC(=S)NC2c2ccccc2F)/C(=C/c2ccccc2F)C1
