The asset market approach explains exchange-rate movements by focusing on demand for financial assets and investors’ expectations of future exchange rates, which determine capital flows and thus currency appreciation or depreciation.

Relevant concepts:
- Asset market approach / portfolio balance: investors choose between domestic and foreign assets based on expected returns, risk, and liquidity.
- Covered/uncovered interest parity (UIP) links interest differentials to expected exchange-rate changes: (1 + i) = (1 + i*) (Ee / E). Linearized: i - i* ≈ (Ee - E)/E, where E is the current price of foreign currency in domestic currency and Ee is the expected future price.
- Short-run vs long-run: asset prices and expectations adjust, producing longer-run shifts in exchange rates.

Step-by-step reasoning and intermediate steps:
1. Compare expected returns: domestic return = (1 + i); foreign return converted to domestic = (1 + i*) (Ee / E). Investors flow into the asset with higher expected return.
2. Using UIP: i - i* ≈ (Ee - E)/E. If i > i*, then (Ee - E)/E > 0, implying Ee > E (investors expect the foreign currency to be more expensive later). Expectations and capital inflows/outflows change current E until returns equalize.
3. If demand for domestic assets rises (due to higher i or improved expectations about the domestic currency), capital inflows appreciate the domestic currency. Conversely, weaker expected returns lead to depreciation. Over time, these asset-market driven flows explain appreciations and depreciations.

Why the correct answer is correct:
- The central implication of the asset market approach is precisely that exchange-rate appreciations and depreciations are driven by shifts in demand for assets and expectations, producing longer-run movements in currencies.

Why other options are incorrect or incomplete:
- "It is based on changes in demand for domestic versus foreign financial assets" is a true element of the approach, but it describes a mechanism rather than the primary summary statement the question targets.
- "It says relative rates of interest and expected strengthening/weakening of currencies determine demand for domestic versus foreign goods and services" is incorrect in wording: the asset-market approach determines demand for financial assets (not directly for goods and services).
- "All of these" is therefore incorrect because the third option’s wording about goods and services is wrong.

Conclusion: The asset market approach explains appreciations and depreciations in the long run, which matches the provided correct answer.
