Option (d).
Explanation:
Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.
Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.
Thus, the correct answer is option (d).

The corpus callosum corresponds to a leaf-shaped structure, being a group of nerve fibers that join both hemispheres of the brain (right and left). This structure is formed by axons covered with myelin, which make up the white substance. The functions of the corpus callosum are: transmission of information to both hemispheres, participation in vision (in eye movement), learning, information processing. When performing surgery on the corpus callosum, syneresis, comprehension disorders may occur
This procedure can be used for epilepsy.
