Vedclass · Answer

(B) $1$. Ladybird is a beetle (insect),not a bacterium. So,option $A$ is incorrect.$2$. Antibiotics have significantly improved the treatment of deadly diseases such as plague $(Black Death)$,whooping cough $(Kali Khansi)$,diphtheria,and leprosy $(Kusth Rog)$. So,option $B$ is correct.$3$. Biogas plants produce a mixture of gases,primarily $CH_4$ (methane),$CO_2$ (carbon dioxide),and $H_2$ (hydrogen),not $H_2S$ as the primary component. While trace amounts may exist,the standard composition is $CH_4, CO_2,$ and $H_2$. Thus,option $C$ is technically less accurate than $B$.$4$. Microbes (methanogens) are essential for biogas production. So,option $D$ is incorrect.Therefore,the most accurate statement is $B$.
