Correct answer: D. Step 1: Identify that aluminum carbide (Al4C3) contains Al3+ and C4- ions. Step 2: On hydrolysis, the C4- ion reacts with protons from water to produce methane (CH4) gas. Step 3: Carbides that yield methane upon hydrolysis are classified as methanides. Thus, Al4C3 is an ionic methanide, corresponding to option (b).
