Answer:
Correct Answer: 1.( a )
Solution:
Bacillus thuringiensis is a source of Cry- proteins. Thermus aquaticus is a source of thermostable DNA polymerase (Taq polymerase) used in PCR. Agrobacterium tumefaciens is a plant pathogen and not a cloning vector. The construction of $1^{s t}$ recombinant DNA molecule was performed using native plasmid of Salmonella typhimurium.
