Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.939\% 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: Cc1cccc(C)c1NC1=NC2(CCCCC2)N=C(N)N1
b: CCOC(=O)CN1C(=O)C(O)(CC(=O)c2ccccn2)c2ccccc21
c: O=C(NCc1ccco1)C1(c2ccc(Cl)cc2)CCCC1
d: O=C(Cn1c(=O)oc2cc(S(=O)(=O)N3CCCCC3)ccc21)N1CCCCC1
e: COCCNC(=S)N/N=C(\C)c1cccc(OC)c1
Answer: e. COCCNC(=S)N/N=C(\C)c1cccc(OC)c1
