Task: Answer the multiple-choice question.
Query: Which drug exhibits a 21.591\% 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 other words.
Options:
a: CCOC(=O)C1CCCN(C(=O)c2ccccc2NC(=O)C2=C(C)OCCS2)C1
b: CCOP(=O)(OCC)c1ccc2c(c1)C(=O)c1ccccc1CC2
c: Cc1cc(NC(=O)CSc2nnc(C(C)N(C)C)n2-c2ccc(F)cc2)no1
d: Cc1csc(NC(C)c2nc3cc(C(F)(F)F)ccc3n2CCCO)n1
e: Cc1nn(CC(=O)NC(C)c2ccccc2)c(=O)c2ccccc12
Answer: a. CCOC(=O)C1CCCN(C(=O)c2ccccc2NC(=O)C2=C(C)OCCS2)C1
