Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.148\% 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 additional words.
Options:
a.) O=P(O)(O)CCP(=O)(c1ccccc1)c1ccccc1
b.) Cn1c(=O)[nH]c(=O)c2c1nc(N1CCOCC1)n2CCCSc1ncccn1
c.) CSc1ccc(/C=C/C(=O)OCC(=O)NC(C)C)cc1
d.) CCN(CC)C(=S)NC(=O)c1cc(OC)c(OC)c(OC)c1
Answer: b. Cn1c(=O)[nH]c(=O)c2c1nc(N1CCOCC1)n2CCCSc1ncccn1
