This is because your question is this "</span>____________ do not share your details online" A. "It's better to" And B. "I advice you to" is incorrect in this situation because both of those answer are inaccurate and make no sense. D. "A<span>ccording to me" is very tricky many people would've picked this answer. But C is correct because the person is making an opinion about what he or she thinks about what should be done online. </span><span> Glad to help :) </span>
