D Correct answer
Explanation

ServletRequest.getInputStream() is declared in the ServletRequest interface and returns a ServletInputStream for reading the request body as binary data. Options A, B, and C are wrong because getMethod(), getHeader(), and getCookies() are declared in HttpServletRequest (which extends ServletRequest), not in ServletRequest itself. ServletRequest contains fundamental methods like getParameter(), getAttribute(), getInputStream(), and getReader(), while HttpServletRequest adds HTTP-specific methods.
