Statement (I) is incorrect: Uredospores (urediniospores of rust fungi like Puccinia) are dikaryotic spores that lack any locomotory appendages (such as flagella) and are completely non-motile, being passively dispersed by wind currents.
Statement (II) is accepted as correct according to the Official NTA Answer Key (Option 4): In plant virology context, viral movement is often categorized as active cell-to-cell mobility mediated by viral movement proteins (MP) through plasmodesmata and systemic vascular mobility through the phloem sieve tubes. (Note: In strict microbiological terms, viral virions lack independent motility organs outside a host, but official key recognizes systemic motility in host tissues).
