Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -32.127\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(CN1CCN(Cc2ccc(Cl)cc2)CC1)N1CCc2ccccc21
b. c1ccc(-c2cc3c(NCC4COc5ccccc5O4)ncnc3s2)cc1
c. CCC(C)NC(=O)CN1C(=O)NC2NC(=O)NC21
d. CC(/C=N/NC(=O)CN1CCN(Cc2ccc(Cl)cc2)CC1)=C\c1ccco1
Answer: a. O=C(CN1CCN(Cc2ccc(Cl)cc2)CC1)N1CCc2ccccc21
