Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.952\% 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. COc1ccc(N/N=C(/Oc2ccc([N+](=O)[O-])cc2)C(C)=O)cc1
b. O=C(CCn1c(=O)[nH]c2ccsc2c1=O)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
c. CC(OC(=O)c1ncc(Cl)c(Cl)c1Cl)C(=O)NC1CCCCC1C
d. COc1cccc(NC(=O)c2cnc(SCC(=O)NCc3ccc4c(c3)OCO4)n(C)c2=O)c1
Answer: b. O=C(CCn1c(=O)[nH]c2ccsc2c1=O)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
