【参考答案及解析】
Rationale: Security is a key vulnerability of email: there is no guarantee of privacy (and a risk of accidentally sending the message to the wrong person). The other options are significant strengths, however. If you hesitated over D, think about how email can be used for memos/reports/letters, and how many formats (visual, audio) can be 'attached' to email messages.
