Which is the best answer for this cloze passage.

I feel that the answer should be 'develop' but many say it should be 'expand'. Kindly comment.

The cloze passage:

The infrastructure development projects proposed in Budget 2011 are welcomed in the Klang Valley as they would certainly improve the quality of life. However, industry experts commented that both widespread planning and follow-up action must be in place to ensure that funds allocated for the projects are used effectively.
One of the projects proposed is the 100-storey Warisan Merdeka which has become the hottest topic. Many people have expressed concern over adding a mega structure to the congested city. They want more information on the purpose of the RM5 billion skyscraper. The Malaysian Institute of Planners� honorary secretary Lee iLh Shyan, said the government should provide more details on the purpose of Warisan Merdeka.
With buildings soaring higher, roads are also to _________________ under the budget with six new highways such as the Ampang-Cheras-Pandan Elevated Highway, Guthrie-Damansara-PJ Highways and Pantai Barat-Banting-Taiping Highway. The traffic planning consultant, Goh Bok Yen believes that these highways will serve the purpose of dispersing traffic and easing bottleneck jams.
A expand
B develop
C increase
D improve
