• (a) Carrot and potato - Carrot is a tap root and potato is a storage stem. So, they are not homologous structures.
• (b) Carrot and tomato  - Carrot is a tap root and tomato is a fruit. So, they are not homologous structures.
• (c) Radish and carrot  - Carrot and radish are tap roots. So, they are homologous structures.
• (d) Radish and potato - Radish is a tap root and potato is a storage stem. So, they are not homologous structures.

  So, the correct answer is (c).
