| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). | 
| 3. | (A) is true but (R) is false. | 
| 4. | Both (A) and (R) are false. | 
| I: | the malarial parasite. | 
| II: | true spores of slime moulds. |
