Option A - INCORRECT.)
If the pharmaceutical industry has increased their public relations spending in order to counter the activity of the animal rights group as claimed in this option A, then there won't be a claim or need for substituting in their place alternative methods of product testing.

Option B - INCORRECT.
The statement in this option is right. However, before the new methods of testing products are used, they have to be calibrated by comparison tests involving experiments on laboratory animals, which still overrides the idea to stop industrial corporations from using Animals in laboratory by the political pressure groups.

Option C - INCORRECT.
When companies stop using laboratory animals, they generally go to some expense to publicize this change of policy which might not be cost effective compared to when the use of Animal in laboratory still trend and there is no need for publicity.

Option D - CORRECT.
This option has seriously cast a strong doubt on the connection between the pressure groups and corporate change claims. The industrial size of the manufacturers using Animals for laboratory test does not stop the political pressure group publicity ban on the eradication of the use of Animals in the laboratory.

Option E - INCORRECT.
The methods of product testing that do not involve laboratory animals are faster and cheaper than the methods that do is a claim that can not be proven. However, if this claim has been true, there won't be need for the political pressure group publicity.
