Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.048\% human ether-à-go-go related gene (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) COc1cccc2c(=O)c3cccc(N)c3[nH]c12
b) CCOC(=O)C1=C(C)Nc2ncnn2C1c1cc(OC)ccc1OC
c) O=C(c1cnc2n(c1=O)CCS2)N(C1CCCCC1)C1CCCCC1
d) Cc1cccc(-n2ncc3c(NC(C)C)ncnc32)c1
Answer: c. O=C(c1cnc2n(c1=O)CCS2)N(C1CCCCC1)C1CCCCC1
