The Correct Option is B

Solution and Explanation

Step 1: Understanding the Concept:
Rhabdoviruses are enveloped, negative-sense single-stranded RNA viruses belonging to the order Mononegavirales.
The best-known member is the rabies virus, which possesses a characteristic bullet-shaped morphology and an immunogenic surface glycoprotein (G protein).
Detailed Explanation:
Statement A: Belongs to Mononegavirales
This statement is correct.
The family Rhabdoviridae is classified under the order Mononegavirales, which includes viruses having a non-segmented negative-sense RNA genome.
Statement B: G protein is immunogenic protein
This statement is also correct.
The G (glycoprotein) present on the viral envelope is the major antigen responsible for inducing neutralizing antibodies and protective immunity.
Statement C: Bullet or Cone shaped virus
This statement is true.
Rhabdoviruses are characteristically bullet-shaped (sometimes described as cone-shaped), making them easily identifiable under electron microscopy.
Statement D: Non enveloped DNA virus
This statement is false.
Rhabdoviruses are enveloped RNA viruses, not non-enveloped DNA viruses.

Step 2: Final Answer:

Statements A, B and C are true, whereas D is false.
\[ \boxed{(B) A, B and C only \]
