Task: Answer the multiple-choice question.
Question: Which drug exhibits a -13.268\% 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=C(C(=O)N1CCOCC1)c1cn(Cc2ccccc2Cl)c2ccccc12
b. O=S(=O)(c1ccc2c(c1)nc1n2CCC1)N1CCOCC1
c. O=C(COc1ccccc1Cl)NC(=S)Nc1cccc(NC(=O)c2ccccc2Cl)c1
d. O=C(NCc1ccco1)C1CCN(S(=O)(=O)N2CCOCC2)CC1
Answer: b. O=S(=O)(c1ccc2c(c1)nc1n2CCC1)N1CCOCC1
