Since the peanuts are so much bigger then granules of sugar, paper filter wouldn’t separate them sugar isn’t fine enough, there’s no magnet in either and stove wouldn’t do anything so it must be strainer
        
                    
             
        
        
        
The correct answer is option C, that is, the presence of the nuclear membrane.  
Cyanobacteria is a phylum of bacteria that attain their energy via the process of photosynthesis, and are the only photosynthetic prokaryotes possessing the tendency to generate oxygen. As a prokaryote, they are devoid of the nuclear membrane.  
Euglena refers to a single cell flagellate eukaryote. It comes under the class Euglenoidea. The species of Euglena are witnessed in salt water and in freshwater. Being a eukaryote, they possess nuclear membrane.  
 
        
                    
             
        
        
        
First calculate the probability of type AB, which is the remainder after subtracting types A, B and O.
P(AB) = 1-(0.34+0.12+0.5) = 1-0.96 = 0.04
Anti-b will react with types B and AB, so 
P(reaction) = P(B)+P(AB) = 0.12 +  0.04 = 0.16
Answer: For this person, the probability of reaction with anti-b is 0.16
