(B) Lamarckism,proposed by Jean-Baptiste Lamarck,is based on two main principles: $1.$ Use and disuse of organs,and $2.$ Inheritance of acquired characters. Option $D$ refers to the 'Use and disuse' theory. Option $C$ refers to the 'Inheritance of acquired characters'. Option $A$ is also associated with Lamarck's view that environmental changes induce new needs in organisms. However,Option $B$ ('Variations lead to differential survival rates') is a core concept of Darwinism (Natural Selection),not Lamarckism. Therefore,it is not a concept of Lamarckism.
