"A complete restriction digestion of a circular plasmid (5000bp) was carried out with HindIII, BamHI and EcoRI individually. Restriction digestion yielded following fragments.
Plasmid + HindIII → 1200bp and 3800bp
Plasmid + BamHI → 5000bp
Plasmid + EcoRI → 2500bp
The number of sites for EcoRI, BamHI and HindIII present on this plasmid are"
A. EcoRI-2; BamHI-1; HindIII-2
B. EcoRI-1; BamHI-1; HindIII-2
C. EcoRI-3; BamHI-2; HindIII-1
D. EcoRI-2; BamHI-2; HindIII-1
