What is one of WHO's objectives?

One of the key objectives of the World Health Organization (WHO) is to ensure universal health coverage. This goal aims to provide all people with access to quality essential health services without experiencing financial hardship. Universal health coverage is crucial for improving health outcomes and promoting equity in healthcare access, allowing individuals and communities to receive necessary services such as preventive care, treatment, and rehabilitation. Ensuring that everyone can access healthcare contributes to overall societal well-being and economic stability, aligning with WHO's mission to promote health and prevent disease on a global scale.

The other options, while they may touch on aspects of public health or development, do not represent WHO's primary objectives. For instance, completely eliminating all diseases worldwide is not feasible or realistic, as new diseases can emerge and existing ones can evolve. Supporting pharmaceutical production and improving agricultural practices can be part of broader health strategies but are not specific aims of WHO as they relate more to individual sectors than to global health coverage directly.
