Task: Answer the MCQ question.
Query: Which drug exhibits a 10.754\% 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 other words.
Options:
(a) O=C(CCC(=O)Nc1ccc(Br)cc1)N/N=C/c1ccccc1F
(b) Oc1ccc(O)c(/C(=N/Nc2ccccc2)c2ccccc2)c1
(c) O=C(NCCc1c[nH]c2ccccc12)C(F)(F)F
(d) O=C1C=C(c2ccc(O)cc2)C[C@@H](c2ccc3c(c2)OCO3)C1
Answer: a. O=C(CCC(=O)Nc1ccc(Br)cc1)N/N=C/c1ccccc1F
