To solve this problem, we need to match the contraceptive methods in List I with their corresponding types in List II. Let's analyze each method:$\newline \bullet$A. Vasectomy:$\newline$ - Vasectomy is a surgical procedure for male sterilization or permanent contraception.$\newline$ - This matches with III. Surgical method.$\newline \bullet$B. Coitus interruptus:$\newline$ - Coitus interruptus, also known as the withdrawal method, is a natural method of contraception.$\newline$ - This matches with IV. Natural method.$\newline \bullet$C. Cervical caps:$\newline$ - Cervical caps are barrier devices that fit over the cervix to prevent sperm from entering the uterus.$\newline$ - This matches with II. Barrier method.$\newline \bullet$D. Saheli:$\newline$ - Saheli is a non-steroidal oral contraceptive pill used by women.$\newline$ - This matches with I. Oral method.$\newline$Now, let's match the items from List I with List II:$\newline A \rightarrow III, B \rightarrow IV, C \rightarrow II, D \rightarrow I \newline$This corresponds to Option 2.
