Answer:
When an E.coli cell is infected by multiple phages,they will take either lytic or lysogenic pathway.
Explanation:
When lambda phage bacteriophage infects an E.coli,it can either undergo lytic cell growth and lyse the host cell or enter lysogenic pathway.
The operator region of lac operon in E.coli contain single repressor binding site whereas the lambda operators 
and 
each contains 3 repressor binding sites (
and 
) that are differently occupied under different conditions.
The differential affinity of lambda repressor for the three binding sites in these operators play an important role in the maintenance of lysogenic state of lambda prophage in E.coli.
The lytic development occurs in cells infected with lambda phage that carry 
gene.
In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.
The fraction of offspring that the Punnett square predict will be tall is ¾ (option C).
<h3>What is the punnet square?</h3>
The punnet square is a graphical representation used to determine the probability of an offspring expressing a particular genotype.
The punnet square is used to predict the percentage or proportion of offsprings of a cross that possess a specific genotype.
According to this question, a punnet square shows a cross between two tall pea plants. The allele for tall height (T) is said to be dominant while the allele for short height (t) is recessive.
If two heterozygous genotype crosses i.e. Tt × Tt, the percentage of offsprings that will be tall is 75% or ¾.
Therefore, the fraction of offspring that the Punnett square predict will be tall is ¾.
