I would answer as follows:
1. Research costs = 200,000+100,000 = 300,000
2. Development costs = 400,000+150,000+150,000 = 700,000
3. You can capitalize only development costs ie. 700,000
4. As per IAS 38.54, you need to charge all research cost to expense. Costs of introduction of the product to experts do not relate to either research or development costs in my opinion.
