Answer D

Its Risk Thresholds - Once you indentify risk then only you can indenfiy that risk's thresholds. Rest other three are used as inputs to indentify risks.

Risk management plan will also include risk categories and risk thresholds.

Si I think its A.Historical Information as we are identifying new project risk and historical information may not be that helpful.

 Still looking for some explanation from experts.

History will give you valuable inputs on whether a particular risk materialized or not in past, whether its a real risk or something which can be ignored.

 I would go with answer D. Though risk threshold details are available in risk management plan, we really don't use them during '  Identify risk' process.  The rest of the 3 are inputs to Identify risks, refer PMBOK guide, identify risk process inputs .1 in pg 284 and .11 in pg 286

The answer should be D.

I have verified with the PMBOK and the historical information is used as input as part of Checklists for Identify Risks process.

this question is based on pmbok 3. see appendix A p356.

In pmbok 4 these all options are included in risk man. plan.

And RMP is input to IR thus all options are indirectly input of IR.

pmi in each revesion makes some changes, like risk identification to identify risk and also changes various contents like - input/output/tts etc.

but Questions based on then editions remains continue, and we generally take the terms as usual in the current meanings, bks we havn't seen the old versions.

so be careful, in pmbok 4 backside appendix are useful when such identical terms (but not exact) come across during study.

The answer is definitely A.

Here is why -

1. Risk Thresholds and Risk categorizations are very much outputs of Plan Risk Management. So there is good reason to expect they are part of the Risk Management Plan.

2. The Identify Risks process doesn't need historical information as an input, which is what the question really is. The historical info, if at all input to any, would be an input to Plan Risk Management, not to Identify Risks.
