Simplify the argument -

1970
New Standards --> 1. Not necessary 2. Not economically viable.

However,
Catalytic Converters --> Made following standards economically viable.

Now
New Standards --> 1. Not necessary 2. Not economically viable.

We need to strengthen the above argument.

Option A - Correct.
More stringent regulations --> less economical. Strengthens the argument above.

Option B - Incorrect.
If it does not reduce efficiency, then the conclusion "not economically viable" falls apart. Weakens the argumeent.

Option C - Incorrect.
We are not sure whether this legislation requires new technology or not. Moreover, we do not know what impact this new technology will have. If it makes it more economical, then the author's argument is weakened.
If it does not require, then probably companies can achieve low emissions with something already existing and cheap.

Option D - Incorrect.
We do not know whether the actual numbers of automobiles increased on the roads from 1970s or not.
Anyways, this is not relevant as we are not interested in such conditionals. We already know that the government HAS made the regulations more stringent. We are asked to evaluate the impact.

Option E - Incorrect.
We are not interested in other cases where the government does not make following the regulations mandatory.
We are interested in this specific case in which the government has made the regulations more strict.
