The question asks us to identify which seeds were sprouted by the Indian Space Research Organisation (ISRO) in space under microgravity conditions in 2025. The correct answer to this question is Cowpea seeds.

Let's break down the solution step-by-step:

1. Background: ISRO, the Indian Space Research Organisation, is known for its contributions to space research and innovation. Conducting experiments in space, especially under microgravity conditions, can provide significant insights into biological and physical processes that are not possible under Earth's gravity.
2. ISRO's Experiment in 2025: In an effort to study how plants grow under microgravity conditions, ISRO sprouted cowpea seeds in space. This type of research is important for future space missions, where growing food on-board spaceships or space stations could be crucial for long-term space habitation.
3. Rationale for Cowpea Seeds: Cowpea (Vigna unguiculata) is a versatile and nutritious legume, often chosen in agricultural research for its robustness in various environmental conditions. Its short growth cycle makes it an ideal candidate for such experiments.
4. Eliminating Other Options:
   • Soya bean seeds: While they are also a common choice for agricultural research, the specific experiment by ISRO in 2025 focused on cowpea seeds.
   • Chickpea seeds: Similar to soya beans, chickpeas are not the seeds specified in this research.
   • Kidney bean seeds: Though kidney beans could potentially be used in such experiments, they were not included in the 2025 ISRO study.

Thus, the correct answer is that ISRO sprouted cowpea seeds in space under microgravity conditions in 2025.
