The correct answer is B. 64%, based on findings from the International Data Corporation (IDC) study Sustainability: From Compliance and Risk Management to Creating Business Value, sponsored by Cisco and published in May 2023.

The study examined sustainability priorities and organizational maturity among 1,244 organizations worldwide.

IDC reported:

64% of survey respondents worldwide view sustainability as a very or extremely important business priority

The figure combines respondents who classified sustainability as either extremely important (33%) or very important (31%).

This finding demonstrates that environmental sustainability has become an important consideration in organizational strategy, technology investment, operational management, and business planning.

Technology professionals contribute through energy-efficient infrastructure, emissions monitoring, digital automation, sustainable procurement, and electronic waste reduction.

However, IDC also found that approximately half of surveyed organizations remained in the early stages of developing comprehensive sustainability strategies with measurable targets.

This distinction emphasizes that identifying sustainability as a business priority does not necessarily indicate mature implementation.

Cisco supports organizations in progressing from strategic commitments toward measurable sustainability performance through energy-efficient technology, infrastructure optimization, and circular economy solutions.

Options A, C, and D do not correspond to the reported IDC figure.
