<p>A and B are the same meaning, he even said in the answer explanation, To be cognizant of something is to be informed about or AWARE=WARY of it.</p>
<p>Surely (A).</p>
<p>“wary of” has negative connotations. But since he “denied” etc. he could not be claiming something negative.</p>
<p>“cognizant” does not by itself have negative connotations. It is simply a statement that he knew of her work.</p>
<p>oh, thank you fogcity, I get it now.</p>
<p>I’m sure Cognizant and wary are completely unrelated to each other… Cognizant of is used to indicate that someone is fully informed about something, but wary of means that someone doesn’t trust people completely as in I’m wary of strangers. I’m cognizant of strangers would, however, give an indication that you know everything about strangers.</p>
