Question

which of the following is not biofertilizers a number is 8 or vector B bacillus trendings C cluster d m d a jeweller

Answer 1

I didn't understand your question because there are some mistakes in it. Correct options are discussed in another website.  So, I assume it as:  

Biofertilizers are used to increase the fertility of soil by adding nutrients in it.Biofertilizers are as follows:

1. Rhizobium

2. Azotobacter 

3. Azospirillum

4. Phosphate Solubilizing Bacteria
 5. Mycorrhiza

6. Blue-green algae

7. Phosphobacteria

As vectors and jeweler are not biofertilizers.

Hope this will you.
