Answer 1

Step 1: Understand the table:
Each row gives either a method of birth control or an example of it. We must fill the missing cell in each row.
The four gaps are a, b, c and d.

Step 2: Find a:
A diaphragm is a rubber cap placed over the cervix to stop sperm from reaching the egg. So the method in row 1 is a barrier method. a = Barrier method.

Step 3: Find b:
Female sterilisation is done by cutting and tying the fallopian tubes. The surgical procedure is called tubectomy. b = Tubectomy.

Step 4: Find c:
Saheli is a non-steroidal pill taken once a week, developed at CDRI Lucknow. It is an oral contraceptive. c = Oral contraceptive pills.

Step 5: Find d:
Cu-T is a copper-releasing device placed inside the uterus. It is an intrauterine device. d = Intrauterine device (IUD).

Final Answer:
a = Barrier method, b = Tubectomy, c = Oral contraceptive pills, d = Intrauterine device (IUD).
