Task: Answer the multiple-choice question.
Question: Which drug exhibits a -7.530\% 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) COc1ccc(O[C@H]2C=C[C@@H](c3ccccc3)O[C@@H]2COC(=O)CC/C(C)=N/O[C@H](C)c2cn([C@@H]3COC[C@H]3O)nn2)cc1
(b) Cc1ccc(/C=N/Nc2ncnc3nc[nH]c23)cc1
(c) CC1=NC(Nc2nc(C)c3ccccc3n2)=NC(C)(C)C1
(d) Cc1ccc(NC(=O)CN2CCC(Cc3ccccc3)CC2)cc1S(=O)(=O)N(C)C.O=C(O)C(=O)O
Answer: b. Cc1ccc(/C=N/Nc2ncnc3nc[nH]c23)cc1
