Separating the three motives by their driving variable:
Keynes' liquidity preference theory lists three motives for holding money: transactions and precautionary demand, both driven mainly by the level of income (people hold more cash day-to-day and for emergencies as their income rises), and speculative demand, driven mainly by the rate of interest. This three-part breakdown itself is accurate, so Assertion (A) is true. Reason (R), however, assigns speculative demand to income rather than interest rate. Under Keynes' theory, when interest rates are low, bond prices are high, so people expect rates to rise (and bond prices to fall) and prefer holding cash speculatively; when interest rates are high, they prefer bonds over idle cash. This is an inverse relationship with the interest rate, not a "direct and positive function of money income" as (R) claims. Because (R) misattributes the driving variable, it is false, leaving (A) true and (R) false, which is option (3).
