Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -1.772\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COCCn1c(-c2ccc(OC)cc2)c(-c2ccc(OC)cc2)oc1=O
(b) CCNC(=S)N1CCC(c2nc3ccccc3s2)CC1
(c) Cc1ccc(S(=O)(=O)Nc2ccc(C(=O)NCc3ccncc3)cc2)cc1
(d) O=C(c1cccs1)N1CCN(S(=O)(=O)Cc2ccccc2)CC1
Answer: a. COCCn1c(-c2ccc(OC)cc2)c(-c2ccc(OC)cc2)oc1=O
