<p>The blank requires a <strong>noun</strong>, and the meaning should refer to <strong>“the people who were chosen”</strong>, not <strong>“the act of choosing.”</strong><br>When <em>selection</em> means “the chosen person or candidate,” it is <strong>countable</strong>, so the plural form <strong>“selections”</strong> is appropriate.</p><p>If the sentence were referring to the <strong>process of choosing</strong>, <em>selection</em> could be either countable or uncountable, but it is usually used in the <strong>singular form</strong> and would not normally be followed by <em>for</em>. In that case, we would say: <br></p><p>The <strong>selection process</strong> for the regional sales manager position.<br></p><p>Therefore, “selections” fits best here because it refers to the <strong>chosen candidates</strong> presented by the committee.<br></p><p><strong>(A) selection</strong> → Singular noun meaning “the act of choosing.” Doesn’t fit naturally with <em>for</em> when referring to people.</p><p><strong>(C) selecting</strong> → Gerund form of a verb; means “the act of selecting,” but the sentence describes <em>the result</em>, not the action.</p><p><strong>(D) selectable</strong> → Adjective meaning “able to be selected,” grammatically incorrect here.</p>
