Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.367\% 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, d, or e without using any other words.
Options:
a: CC(C)Oc1ccc(C(=O)N2CCCc3ccccc32)cc1
b: O=C(COc1ccc(-c2ccccc2)cc1)NN=C1CCCC1
c: CCCCCCn1c(N2CCC(C(N)=O)CC2)nc2c1c(=O)[nH]c(=O)n2C
d: O=C(CSc1nc2c(sc3ccccc32)c(=O)n1Cc1ccccc1)NCC1CCCO1
e: CCOCCCNC(=O)C1CCCCN1S(=O)(=O)c1ccc(F)cc1
Answer: b. O=C(COc1ccc(-c2ccccc2)cc1)NN=C1CCCC1
