Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.198\% 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.) Cc1c(CCC(=O)N[C@@H](CCCNC(N)=O)C(=O)O)c(=O)oc2cc3oc4c(c3cc12)CCCC4
b.) Br.Nc1ccc(OCC(O)C[n+]2ccc(CCS(=O)(=O)[O-])cc2)cc1
c.) C=CCn1c(C(C)NC(=O)c2cccs2)n[nH]c1=S
d.) CCNC(=O)N1c2ccc(OCC)cc2C(C)=CC1(C)C
Answer: d. CCNC(=O)N1c2ccc(OCC)cc2C(C)=CC1(C)C
