Each of the choices may be considered right depending on the use of context or on how terms are defined, but the one that is most correct is:

"Controlled experiments produce valid data"

Controlled experiments are experiments in which factors which are not the interest of the study or which are not being studied are controlled or accounted for in the design, so that resulting data are less likely to be caused by some anomaly or by some variable other than those being studied. In usual research scenarios it is not the data itself that is acted upon in the experiment - it is the experiment itself, the factors and the physical processes that will eventually yield data.
