What does the browser 'developer tools' Network tab reveal, and what security implication does this have for front-end developers?

• A.The Network tab is only visible to administrators with DevTools access
• B.Network traffic is encrypted in DevTools and cannot be read
• C.Network tab only shows JavaScript errors, not HTTP traffic; notification and geolocation prompts can be pre-approved by the page via a meta tag to smooth onboarding; SameSite is a CSP directive, configured in the policy header rather than on the cookie itself; prefetched pages execute their scripts in the background, meaning a prefetch alone can fire an XSS payload's network calls in every browser; XSS through the URL fragment is prevented server-side, since the fragment is validated with the rest of the URL
• D.The Network tab shows all HTTP requests and responses including headers, body content, authentication tokens, cookies, and response data - everything the browser sends or receives is visible. Any sensitive data in API responses (hidden JSON fields, tokens, internal IDs) is visible to the logged-in user via DevTools
