Witch statement about this figure is false

I believe the answer is layer c is the youngest layer

Option (2) and (3)

Explanation: From the figure, we can mark that the layer I is the oldest of all, which got tilted along with the overlying rock layers namely H, G and F, which are eventually cut by a fault represented as line E.

                  Here C is not a layer. It is just a river valley that cuts the rocks of layer A and B.

                     Layer K is the youngest of all as it recently got intruded through the rocks from the bottom to the top.

thus, the correct answers are (2) and (3).

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

I’m not really sure
