Which of the following definitions best describes '2'-N-acetylparomamine'?

A. An aminoglycoside composed of glucose deoxygenated at C-4 and C-6 and having aminoethyl, methyl and 3-hydroxy-3-methylbutanamido substituents at positions 1, 2 and 4, respectively.
B. An anthracycline antibiotic that is produced by Streptomyces galilaeus and also has potent antineoplastic activity.
C. An aminoglycoside that is 2-deoxystreptamine that is substituted on the oxygen at position 4 by an (8R)-2-amino-8-O-(4-amino-4-deoxy-alpha-D-glucopyranosyl)-2,3,7-trideoxy-7-(methylamino)-D-glycero-alpha-D-allo-octodialdo-1,5:8,4-dipyranos-1-yl) group.
D. An aminoglycoside that is 4alpha,6alpha-diaminocyclohexane-1beta,2alpha,3beta-triol in which the pro-R hydroxy group has been converted into its 2-acetamido-alpha-D-glucoside derivative.

Answer: An aminoglycoside that is 4alpha,6alpha-diaminocyclohexane-1beta,2alpha,3beta-triol in which the pro-R hydroxy group has been converted into its 2-acetamido-alpha-D-glucoside derivative.
