Statement I : An ideal contraceptive should be user-friendly, easily available, effective and reversible with no or least side-effects.
Statement II : Natural methods work on the principle of avoiding chances of ovum and sperms meeting.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Both Statements I and II are correct.
A contraceptive is a method used to prevent unwanted pregnancy. The book gives the qualities of an ideal one, and then groups the methods by how they work. Natural methods use no device or drug; they only stop the ovum and sperm from meeting.
Statement I: An ideal contraceptive should be user-friendly, easily available, effective and reversible with no or least side-effects. — True. These are the qualities the book lists for an ideal contraceptive. It should also not interfere with the sexual drive or the sexual act of the user.
Statement II: Natural methods work on the principle of avoiding chances of ovum and sperms meeting. — True. Periodic abstinence, withdrawal and lactational amenorrhea are natural methods. All of them work by avoiding the meeting of ovum and sperms.
