Question 1194009
.


If the question is


<pre>
    "Choose all the descriptions for natural numbers n that have {{{highlight(EXACTLY)}}} / {{{highlight(PRECISELY)}}}  3  divisors"
</pre>

then your answer " option &nbsp;4 " &nbsp;is correct.




As the question is worded in the post, &nbsp;it may have hidden &nbsp;EXTENDED &nbsp;meaning, &nbsp;and then the the answer &nbsp;" ALL " &nbsp;is applicable.



I understand that the &nbsp;" option 4 " &nbsp;is the first answer which comes to the mind,
but the answer &nbsp;" all options " &nbsp;is also possible, &nbsp;formally speaking.



So, &nbsp;this question/problem is consciously and ideally constructed in a way to catch &nbsp;(to cop) 

a person at exam, &nbsp;with all the ensuing consequences . . .
