To determine the appropriate SPF (Sun Protection Factor) range that provides effective protection from UVA and UVB radiation, it's important to understand the common recommendations for sunscreen use. SPF is a measure of how well a sunscreen will protect skin from UVB rays, but a broad-spectrum sunscreen that also protects from UVA rays is key for comprehensive protection.

Out of the provided options:

1) SPF 15; 50
2) SPF 25; 50
3) SPF 15; 30
4) SPF 30; 50

SPF 15 and SPF 50 are widely recognized ranges for effective sunscreen. SPF 15 is often recommended for everyday use, providing adequate protection for many daily tasks, while SPF 50 offers a higher level of protection, suitable for prolonged sun exposure or sensitive skin.

Given these common guidelines and the need for effective and practical sun protection, the most appropriate SPF range that covers the requirements for protection from both UVA and UVB radiation would be 15 to 50.

Thus, the correct answer is:

1) SPF 15; 50
