Read the following paragraph and identify the most correct statement.

Imagine that you were recently hired as a software engineer to a company that specializes in aircraft navigation control software. While orientating yourselves to the company's work practices, you observe that they in fact do not conduct a few tests that they should in order to comply with the relevant safety standard. When you inquire about this from the project manager, he dismisses it saying that those tests are really unnecessary $($and takes an unreasonably long time to conduct, as well as being superfluous$)$ and that they have managed with the other tests for so long, without any problems.

a$.$ You should do nothing and let the matter slide

b$.$ Since you are new to the company, and you are unfamiliar with the internal processes and politics, you should first find$-$out more about the issue and its background

c$.$ You should immediately resign from the company and file a complaint with the relevant standard institution

d$.$ Although you are new to the company, and you hardly know anything about the internal processes and politics, you should insist on the company changing its work practices immediately, failing which you threaten to report the matter
