<p>The correct answer is <strong>(D) plus</strong>.</p>
<p>In this sentence, the phrase "comes with" is used to indicate that the smartwatch has certain features or functions. The word "plus" is used to add on to or include additional features. Therefore, the sentence means that the smartwatch has an Internet connection <strong>in addition to</strong> a variety of other functions.</p>
<p>The other options are not suitable in this context:</p>
<p><strong>(A) beyond</strong> - This suggests that the smartwatch has an Internet connection that goes beyond or exceeds a variety of other functions. This does not make sense in the context of the sentence.</p>
<p><strong>(B) like</strong> - This implies that the smartwatch has an Internet connection that is similar to a variety of other functions. However, the sentence does not compare the Internet connection to other functions, but rather states that the smartwatch has both an Internet connection and other functions.</p>
<p><strong>(C) through</strong> - This suggests that the smartwatch has an Internet connection that is achieved or accessed through a variety of other functions. Again, this does not accurately convey the intended meaning of the sentence.</p>
