Answer 1

Dear respected friend,

As per my information of animal genetics and pathological data the species of Agrobacterium tumefaciens is known to cause a disease called "crown gall tumors" via the Ti Plasmid of the species itself those gall tumours are known to "affect a lot of gymnosperms and some species of Angiosperms which are dicot or dicotyledonous in nature (that is one seed enclosed of two more seeds).

It's often common to refer crown gall disease by connecting it to the main species of Agrobacterium tumefaciens. Here, Ti Plasmid is a Plasmid collectively known to induce tumor and form malignant cells inside the host body of a normal dicotyledonous angiosperm or a gymnosperm.

Therefore, our required option becomes and is definitely a correct one, Option D) All of the above, they cause and spread the disease of "Crown Gall bladder" to other more known hot and "infect them" in family of "Angiosperm being exclusive to dicotyledonous seeds" and "Gymnosperms".

Hope this helps you and clears your doubts for the infective species of Agrobacterium tumefaciens !!!!!
