Task: Answer the multiple choice question.
Query: Which drug has a 3.222\% 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.) CCSC1=NC(C)(C)C=C(C)N1
b.) Cc1ccc(C(=O)Nc2ccc(C(=O)N/N=C/c3ccccn3)cc2)cc1
c.) Cc1ccccc1CNC(=O)C1CCC(=O)N(CC2CCCCC2)C1
d.) O=C(c1ccc2c(c1)OCO2)C1CCCN(Cc2cn[nH]c2-c2cccc(F)c2)C1
Answer: a. CCSC1=NC(C)(C)C=C(C)N1
