Task: Answer the multiple-choice question.
Question: Which drug exhibits a 10.138\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. Cc1cccc(C)c1NC(=O)CN(C)C(=O)c1cccc(S(=O)(=O)N2CCN(c3ccccc3)CC2)c1
b. CNC(=O)C1C(=S)NC(N)=C(C#N)C1c1ccccc1
c. O=C(CN1CCN(c2ccc(Cl)cc2)CC1)NCc1ccccc1
d. O=C(N/C(=C\c1ccc(Br)cc1)C(=O)N1CCOCC1)c1ccc(Br)o1
Answer: b. CNC(=O)C1C(=S)NC(N)=C(C#N)C1c1ccccc1
