To determine the primary advantage of mass appraisal, let's analyze the options provided.

1. Accuracy: While mass appraisal can provide accurate assessments for a large number of properties collectively, individual accuracy may not reach the level achieved through individual appraisals.

2. Timeliness: Mass appraisal systems are often developed to assess properties quickly, particularly for assessment purposes in jurisdictions. This makes timeliness a significant advantage.

3. Cost-effectiveness: Mass appraisal is generally more cost-effective compared to individual appraisals since it utilizes data and statistical methods to assess multiple properties at once.

4. Fairness: Mass appraisal aims to create a fair assessment by using standardized methodologies and data to assess properties rather than relying on individual appraisers' judgments.

Considering these aspects, the most significant advantage of mass appraisal is (c) Cost-effectiveness. It allows for a large number of properties to be assessed efficiently, minimizing costs and maximizing the utility of available resources.
