Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.647\% 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) CCC(CO)Nc1ncnc2onc(-c3ccc(F)cc3)c12
(b) CC1CCCC1/C(=N/O)c1ccccc1
(c) C/C=C(\C)CN1CCN(c2ccccc2F)CC1
(d) O=C(Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1)c1ccc(Br)o1
Answer: b. CC1CCCC1/C(=N/O)c1ccccc1
