Steps to Determine Acceptable TDS Levels

1. Break Down the Problem
   We need to understand the acceptable ranges of Total Dissolved Solids (TDS) in drinking water based on the options provided.

2. Relevant Concepts
   TDS is a measure of the combined content of all inorganic and organic substances contained in a liquid. The acceptable TDS levels in drinking water are typically categorized as follows:

   • 0-150 ppm: Excellent
   • 150-300 ppm: Good
   • 300-500 ppm: Fair

   • 500 ppm: Poor, potentially unsafe

3. Analysis and Detail

   • Option a (50-150 ppm): This range falls within the excellent category.
   • Option b (>500 ppm): This is considered poor and potentially unsafe for human consumption.
   • Option c (0-50 ppm): This is also excellent, but not explicitly listed as an option.
   • Option d (300-500 ppm): This range is considered fair, but still acceptable for human consumption.

4. Verify and Summarize
   The best ranges for TDS levels in drinking water according to health standards indicate that any water with TDS above 500 ppm may pose health risks. Thus, the safest options for human where comfortable levels were provided are within the range of 0-150 ppm and 150-300 ppm. However, since this question does not include clear phrasing for that wider range, focusing on the provided options yields:

Final Answer

The acceptable amount of TDS in water suitable for human consumption is option a: 50-150 ppm.
