Let's look at the options one by one:
<span>a. Science is never used in the wrong way by people trying to prove a point.
-this is wrong! science has been abused in many context in which people were trying to prove their (often mistaken) points: for example, it has been used to justify racism.
b. Science is able to answer society's questions about why life exists.
- this is wrong, as we still don't have an answer as to why life exists.
c. Science is intended to shape the moral views of society.
-this is not always true. Sometimes science is done just to find out new information rather than share views.
d. Science can be used to address societal issues and to inform policy.
-I think that this is the best answer! For example a scientific study in psychology can inform educational policies and a study into the effects of alcohol can inform an informational campaign about the threats of drinking.

We will use the Descartes` rule of signs and see how many times the signs change from positive to negative and from negative to positive from one term to the next ( two consecutive terms are with different signs ).
In this case it is 4 times ( +7x13 to -12x9, -12x9 to +16x5, +6x5 to -23 x and finally -23x to +42 ).
Answer: There are 4 real zeroes.
