| II. Satvinia is heterosporous |
| III. The life-cycle in all seed-bearing plants is diplontic |
| IV. In Pinus male and female cones are borne on different tress |
A) Statements (I) and (III)
B) Statements (I) and (IV)
C) Statements (II) and (III)
D) Statements (I) and (II)
Correct Answer: D
Solution :
