Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.332\% 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 other words.
Options:
a CCOC(=O)C(C)/C(C)=N/NC(=O)CCC(=O)Nc1cc(C)ccc1C
b N#C/C(=N\Nc1ccccc1)C(N)=S
c CC1(C)N=C(c2cccs2)C(C)(C)N1O
d Cc1ccc(S(=O)(=O)N2CCN(C(=O)CSc3nncs3)CC2)cc1
Answer: b. N#C/C(=N\Nc1ccccc1)C(N)=S
