Answer:
As the variables are not given, let us help with general explanation on manipulated variable.
Explanation:
A manipulated variable is an independent variable. In a scientific experiment, an independent variable can be described as a variable which can change naturally or which is changed by the researcher to check its effect on the dependent variable. The dependent variable is the variable which is under study and being tested. 
For example, to check the difference in photosynthesis rate by light, the amount of light will be the independent variable and the rate of photosynthesis will be the dependent variable.

A) water is a polar molecule.     
B) the empirical formula of water is HO.                    
C) the shape of a water molecule is bent. 
D) the molecular formula of water is H2O.
If you are, then the answer would be letter b. the empirical formula of water is HO.<span>  </span>
<span>>Water Molecular Formula</span><span>: H</span><span>2</span><span>O</span>
<span>>Water </span>Empirical Formula: H2O
