Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.423\% 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. O=C(CN1CCCc2ccccc21)N/N=C/c1ccc(O)cc1O
b. CCOC(=O)CCc1c(C)nc(SCc2ccc(C(=O)O)cc2)c(C#N)c1C
c. COc1ccc(-c2csc(N(CCCN(C)C)C(=O)c3ccc(C)cc3)n2)cc1.Cl
d. CCN(CC)CCn1c(=S)[nH]c2cc3c(cc2c1=O)OCO3
Answer: a. O=C(CN1CCCc2ccccc21)N/N=C/c1ccc(O)cc1O
