Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.778\% human ether-à-go-go related gene (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: O=C(CSCc1cnn(-c2ccccc2)c1-n1cccc1)NCCN1CCOCC1
b: Cc1ccc(N2C(=O)c3ccccc3NC2C(C)Cc2ccc3c(c2)OCO3)cc1
c: COc1ccc(C(c2nnnn2C2CCCCC2)N2CCN(c3ccccc3F)CC2)cc1
d: O=C(Nc1ccccn1)c1c(O)c2cccc3c2n(c1=O)CCC3
Answer: d. O=C(Nc1ccccn1)c1c(O)c2cccc3c2n(c1=O)CCC3
