• A. A- 2, B- 1, C- 3, D- 4
• B. A- 2, B- 3, C- 1, D- 4
• C. A- 2, B- 3, C- 4, D- 1
• D. A- 1, B- 3, C- 4, D- 2

Answer 1

The correct option is B A- 2, B- 3, C- 1, D- 4

Red rust of tea is caused by cephaleuros. They also spoil the drinking water and foul the marine vessels.

Haplontic life cycle is characterized by the dominance of haploid phase and no plant body is present with diploid phase.

Cladothrix is a genus of bacteria growing in the form of filaments, and especially characterized by false branching.

Bacteriological filter is a filter, whose pores are fine enough to filter the bacteria and Cosmarium is a bacteriological filter, because its cell membrane is highly porous, that can filter organism as small as bacteria.
