**Core Concept**
The question is testing the knowledge of contraceptive methods suitable for lactating mothers, considering the safety of both the mother and the infant. Lactational amenorrhea method (LAM) is an effective form of contraception that relies on the natural postpartum infertility associated with exclusive breastfeeding.

**Why the Correct Answer is Right**
The correct answer, **C. Lactational Amenorrhea Method (LAM)**, is the most appropriate choice for lactating mothers because it is a non-hormonal method that aligns with the natural postpartum infertility associated with exclusive breastfeeding. LAM requires the mother to be amenorrheic (not having periods), fully or nearly fully breastfeeding, and less than 6 months postpartum. This method takes advantage of the natural suppression of ovulation caused by prolactin, a hormone released during breastfeeding.
