From the options what can be said about this disease is that ( B ) : The Pathogen replicates without using host cells' replication machinery and it is directly transmitted. 
Since The new disease transmits from one person to another via handshake that means that the disease is a directly transmitted disease, also given that the disease can be cured with the use of antibiotics shows that the causative agent is not a virus but a bacteria. bacteria are living organisms with their own machinery for self replication, therefore they do not need the host cell to replicate the disease before transmission. 
Hence we can conclude that the disease is caused by a Pathogen which replicates without using host cells' replication machinery and it is directly transmitted.

Advantages of separated karyogamy and plasmogamy.
Explanation:
In many fungi, the time of nuclear fusion is separated from the time of cytoplasmic fusion . This arrangement benefits by allowing mating and spore formation to occur in different environment.
Karyogamy is the process of fusion of nuclei , this precedes spore formation.
Plasmogamy is the fusion of cytoplasm, this process involves mating.
Mating is succeeded by spore formation. Both the processes are favored by different environmental condition.
