Task: Answer the multiple choice question.
Question: Which drug exhibits a -21.228% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COC(=O)Cn1cc(/C=C/c2cc[n+](C)cc2)c2ccccc21.[I-]
b: COc1cccc(C(C(=O)NC2CCCCC2)N(C(=O)Cc2cccs2)c2ccc(-n3cnnn3)c(OC)c2)c1
c: CCCn1c2c(c(O)c(C(=O)NC)c1=O)CCCC2
d: CCOC(=O)C1CCN(C(=O)CN(c2ccc(OC)cc2)S(=O)(=O)c2c(C)noc2C)CC1
Answer: d. CCOC(=O)C1CCN(C(=O)CN(c2ccc(OC)cc2)S(=O)(=O)c2c(C)noc2C)CC1
