Answer:
Undifferentiated cells which can be converted in any cell type as per need of the body. They originate form embryos and body tissues; like stem cells derived form skin, bone marrow, blood etc. stem cells controversy discusses the ethical boundaries in using stem cells or human embryos. retrieving embryos from the maternal body and using them for stem cell genesis is considered unethical according to most school of thoughts. But, nowadays scientists are shifting towards pluripotent stem cells. using stem cells in research can be very useful as nowadays many therapies include stem cells, like bone marrow transplant. moreover, using embryonic stem cells we can understand how an embryo develops, crossing various stages like fetus, and developing into an organism.

I believe the answer is C
sorry if I am wrong, its been a while since I did something like this
Answer:
A) Tissue
Explanation:
Cells are the basic and fundamental units of all living organisms. Plants, like every other multicellular living organisms, are composed of cells that perform different functions. A group of cells that perform similar functions make up or form TISSUES, tissues that work together form the ORGAN, organs that work together to perform same function form the ORGAN SYSTEM.
In plants, sieve tubes and companion cells work together to carry out a similar task in plants, which is to transport nutrients and sugar inside the plant. Since sieve tubes and companion cells work together to fulfil same task, they collectively form a tissue in plants called PHLOEM tissue.
