Answer:
The correct option is<em> D. Tell the surgeon that the brother-in-law will decide after explanation of the proposed surgery is provided to him and the widow</em>
Explanation:
In the Sub- Saharan region, the customary law allows the inheritance of wife and the culture of having more than one wife is also practised in this region. According to the law, the widow will become the inherited wife of her deceased husband's brother.
In those regions, the woman are suppressed and the regions are male dominant regions. The women have to obey men's command. Hence, it will more likely be that the brother- in- law will make the decision.

Answer:
The correct option is (C). The above mentioned definition is true for biofilm that resembles a slimy structure composed of cells attached to each other. 
Explanation:
  The adherent cells that results due to the formation of biofilm are known to invade the slimy extracellular matrix that are made up of extracellular polymeric substances. These embedded cells serves the function of production of EPS component that is composed of genetic material, polysaccharides and lipids. These biofilms are capable of growth on the living as well as the non living things.  
Formation of biofilm by the microbes occurs due to several factors namely nutritional factors, antibiotic attack and cellular recognition to the attachment site. The defined steps of the biofilm formation includes initial attachment, Irreversible attachment, Maturation I, Maturation II and Dispersion.
