Final answer:
The Security Guard should leave the woman alone as she has a right to breastfeed in public. Directing her to a private area is unnecessary unless she requests guidance.
Step-by-step explanation:
In the scenario where a Security Guard observes a woman breastfeeding her baby in a shopping mall, the correct action to take would be option c) Leave her alone. Breastfeeding in public is a legally protected right in many places, and mothers are not obligated to use private facilities unless they choose to. The presence of a private feeding area does not mean a mother must use it, so the guard should respect her right to feed her child wherever she feels comfortable.
