Detailed explanation-1: -The three bands B2, B3, and B4 which roughly correspond to blue, green, and red light, respectively, are typically used to generate “true color” products by directly mapping these band reflectances to pixel RGB values.
Detailed explanation-2: -To achieve the best results for NDVI and NDWI calculation, RED band is chosen as Band 4, NIR band and SWIR band are selected as Band 8a and Band 11 respectively in Sentinel-2A.
Detailed explanation-3: -To generate a true color composition you need to take the bands from red, green and blue spectrum which in Sentinel-2 are bands 4 (red), 3 (green) and 2 (blue). The last digits of the layer name identify the band. From your screenshots you have bands 8A (Narrow Near Infra Red), 11 and 12 (Short Wave infra Red).
