Preheat oven to 180 degrees C.

Grease or line a 9-inch loaf tin or 2-3 mini loaf tins.

In a mixing bowl, combine flour, baking powder, baking soda, and salt.

Mix dry ingredients well and set aside.

In another large bowl, add eggs and oil.

Beat eggs and oil well using a hand whisk.

Add sugar to the wet ingredients and beat again until combined.

Incorporate orange zest, orange juice, lemon juice, raisins, and grated carrots into the mixture.

Mix until all ingredients are evenly distributed.

Gradually add the flour mixture to the wet ingredients.

Mix until just combined, being careful not to overmix.

Pour the batter into the prepared loaf tin or mini loaf tins.

Bake for approximately 20 minutes, or until a toothpick inserted into the center comes out clean.

The baking time may vary based on the size of the tins.

Allow the loaf to cool in the tin for 10 minutes.

Turn the loaf out onto a wire rack to cool completely before slicing and serving.
