​Which one of the options correctly represents organisms from the subphyla Chelicerata, Myriapoda, and Hexapoda, in this specific sequence?​

Correct option is B

Explanation -

1. Chelicerata
These are arthropods that lack antennae and have chelicerae (mouthparts).
Examples: Arachnids (spiders, scorpions, ticks, mites)
                  Horseshoe crabs
2. Myriapoda
These are multi-legged arthropods.
Examples: Centipedes (Class Chilopoda)
                  Millipedes (Class Diplopoda)
3. Hexapoda
These include arthropods with six legs (three pairs).
Examples:  Insects (ants, beetles, butterflies, springtails, etc.)
                  Springtails (technically Collembola, part of Hexapoda but not true insects)

So, the correct answer is option b -  Horseshoe crabs, centipedes, springtails
