Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.947\% 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 CCCNC(=O)c1oc2ccc3c(c2c1C)C(=O)CC(C)(C)O3
b O=C(CCn1c(=O)oc2ccccc21)NCCC1=CCCCC1
c CCOC(=O)n1c(=O)n(Cc2ccc(Cl)cc2Cl)c2ccccc21
d O=C(CCc1nnc(CCCCc2ccccc2)o1)NC(c1cccnc1)C(F)(F)F
Answer: a. CCCNC(=O)c1oc2ccc3c(c2c1C)C(=O)CC(C)(C)O3
