**Core Concept**
The ideal contraceptive method for a newly married couple planning to delay starting a family should be effective, reversible, convenient, and have minimal side effects. The chosen method should allow for easy return to fertility when desired.

**Why the Correct Answer is Right**
The ideal contraceptive for this scenario is the **progestin-only pill (POP)**, also known as the mini-pill. It is a highly effective form of contraception that works by inhibiting ovulation and thickening cervical mucus to prevent sperm entry. The POP has a lower risk of blood clots compared to combined oral contraceptives and is suitable for breastfeeding women and those with a history of thrombosis. The POP is also reversible, allowing for quick return to fertility when desired.

**Why Each Wrong Option is Incorrect**
**Option A:** The combined oral contraceptive pill (COC) is not ideal for this couple because it contains estrogen, which increases the risk of blood clots, particularly in smokers and those with a history of thrombosis.
**Option B:** The intrauterine device (IUD) is not suitable for this couple as it requires insertion and may cause bleeding irregularities, which may be undesirable in the early stages of marriage.
**Option C:** The male condom is not the ideal choice as it requires consistent use, can be less effective, and may not be as convenient for daily use compared to a pill.

**Clinical Pearl / High-Yield Fact**
The POP is a good choice for breastfeeding women as it does not affect milk supply and has a lower risk of side effects compared to other hormonal contraceptives.

**Correct Answer:** C. Progestin-only pill (POP)
