Concept: ICT means Information and Communication Technology. In disaster management, ICT supports early warning, communication, data sharing, preparedness, monitoring, and response.
Step 1: Identify roles of ICT.
ICT can accelerate disaster preparedness through digital tools, databases, and communication networks.
ICT can create early warning systems through sensors, satellites, alerts, and communication platforms.
ICT can set up emergency communication to enable prompt action and relief.
\[
ICT = \text{Information + Communication + Technology}
\]
Step 2: Check the options which do not directly come under ICT.
Forming public-private alliances is more of an institutional and administrative activity, not a direct ICT role.
Diversity and gender mainstreaming are social inclusion and policy-related concepts, not direct ICT functions.
Step 3: Select the correct combination.
The options that do not directly come under the role of ICT are:
\[
C \text{ and } E
\]
Therefore, the correct answer is C and E Only.
