Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 2.111\% 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) CCCNC(=O)C(CC)NS(=O)(=O)c1ccc(OC)cc1
(b) Cc1ccc(-c2n[nH]c3c2CCC3)cc1
(c) N#C/C(=C\c1ccc(OCc2ccccc2)cc1)C(N)=O
(d) COCC(C)NC(=O)c1ccccc1OC(C)=O
(e) NC(=O)C1CCN(C(=O)c2ccc(C(F)(F)F)cc2)CC1
Answer: c. N#C/C(=C\c1ccc(OCc2ccccc2)cc1)C(N)=O
