The correct option is A.
When an end of a tuning fork that is vibrating is placed against a table, it produces a sounder that is dramatically louder than the original sound produced by the vibrating tuning fork. At this stage, the tuning fork is forcing the table to vibrate at its own frequency. Thus, the statement in option A is not true.
Prophase of mitosis do the chromosomes become distinctly visible in the microscope.
During metaphase, the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell. At this stage, the chromosomes are distinguishable when viewed through a microscope. The first stage of mitosis and of meiosis I and II.
During prophase the chromosomes become visible as distinct structures, the nuclear envelope breaks down, and a spindle forms (Meiotic prophase I is more complex, and includes synapsis of homologous chromosomes and crossing over). During Prophase chromosomes become Clearly visible, nuclear envelope disappears, kinetochores and spindle fibers form.
