Step 1: Understanding stem cells.
Stem cells are undifferentiated cells capable of self-renewal and differentiation into specialized cells.
Step 2: Types of potency.
Totipotent cells can form whole organism, pluripotent form most tissues, multipotent form related cell types, and unipotent form one type only.
Step 3: Nature of adult stem cells.
Adult stem cells are found in tissues like bone marrow and are restricted in differentiation ability.
Step 4: Multipotent characteristic.
They can form multiple but related cell types such as blood cells from hematopoietic stem cells.
Step 5: Evaluation of options.
Thus, adult stem cells are generally multipotent in nature.
Step 6: Final conclusion.
Therefore, option (3) is correct.
