Task: Answer the multiple-choice question.
Query: Which drug exhibits a -11.521% 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 CC(NC(=O)c1ccccc1)C(=O)NNC(=O)c1ccccc1Cl
b Cl.O=S(=O)(c1ccc2nc(COc3ccccc3)[nH]c2c1)N1CCOCC1
c O=C(CN1CCN(Cc2ccccc2)CC1)N/N=C/c1cccnc1
d C[C@H](N)C(=O)N1CCC(C(=O)N[C@@H](Cc2ccccc2)C(=O)Nc2ccc(F)cc2)CC1
Answer: b. Cl.O=S(=O)(c1ccc2nc(COc3ccccc3)[nH]c2c1)N1CCOCC1
