Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.456\% 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 other words.
Options:
a. Cc1[nH]c2ccccc2c1/C=N/NC(=S)NCc1ccccc1
b. COc1ccc(OC)c(NC(=O)CN(c2ccc(C(C)C)cc2)S(=O)(=O)c2c(C)noc2C)c1
c. Cc1ccnc(-n2c(C)cc(/C=C3\C(=O)NC(=S)N(C)C3=O)c2C)c1
d. COc1ccc(CC(=O)c2c(O)cc(O)cc2O)cc1OC
Answer: a. Cc1[nH]c2ccccc2c1/C=N/NC(=S)NCc1ccccc1
