Task: Answer the multiple choice question.
Query: Which drug exhibits a -79.752% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) Cc1cccc(NC(=S)N(C)C)c1C
(b) O=C(c1cc([N+](=O)[O-])ccc1N1CCOCC1)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
(c) CCCOc1ccc(C(C)=O)cc1Cc1c(O)[nH]c(=S)[nH]c1=O
(d) Cc1ccc(COC(=O)CN2C(=O)NC3(CCCC3)C2=O)cc1
Answer: b. O=C(c1cc([N+](=O)[O-])ccc1N1CCOCC1)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
