Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.253\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. COC(=O)[C@]12OC[C@]34C([C@@H](O)[C@@H]1O)[C@]1(C)CC(=O)C(O)=C(C)[C@@H]1C[C@H]3OC(=O)[C@H](O)[C@@H]24
b. Cl.N=c1ccn(Cc2ccc(Cl)cc2Cl)cc1
c. CCCS/C(N)=N/N=C/c1ccccc1O
d. N#CCCN(Cc1cccnc1)C(=S)NC(=O)c1ccco1
e. O=C(CNc1ccccc1Cl)N/N=C1\CCCc2ccccc21
Answer: c. CCCS/C(N)=N/N=C/c1ccccc1O
