Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.148\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC(C)(C)NCC(O)c1cc(O)cc(O)c1.O=S(=O)(O)O
b CN(C)c1ccc(C(=O)C(O)c2ccc(C(C)(C)C)cc2)cc1
c O=C(O)C1OC(Oc2cc3oc(-c4ccccc4)cc(=O)c3c(O)c2O)C(O)C(O)C1O
d Cc1c(C(=O)Nc2ccc3oc(-c4cccnc4)nc3c2)oc2ccccc12
e CCc1occc(=O)c1Oc1cc(NN2CCCCC2)c([N+](=O)[O-])cc1[N+](=O)[O-]
Answer: a. CC(C)(C)NCC(O)c1cc(O)cc(O)c1.O=S(=O)(O)O
