Always draw the regular insulin into the syringe first are the principles to follow when mixing two types of insulin in the same syringe.
When the doctor prescribes you to use two types of insulin for a particular injection, they must be mixed in the same insulin syringe then there will only exist the need of only one injection. Two types of insulin can be helped to keep the blood sugar levels in a particular target range.
When there is a mixing of regular insulin with another type of insulin, always concentrate on drawing the regular insulin into the syringe at first. When there is a mixing of two types of insulins other than particular regular insulin, it will not be a matter of in what order you draw them rightly into the syringe.
So, there should be some basic principles to be followed when mixing two insulin in the same syringe takes place.

Saddam formally rose to power in 1979, although he had already been the de facto head of Iraq for several years. He suppressed several movements, particularly Shi'a and Kurdish movements, which sought to overthrow the government or gain independence,and maintained power during the Iran–Iraq War and the Gulf War. Whereas some in the Arab world lauded Saddam for opposing the United States and attacking Israel he was widely condemned for the brutality of his dictatorship. The total number of Iraqis killed by the security services of Saddam's government in various purges and genocides is conservatively estimated to be 250,000. Saddam's invasions of Iran and Kuwait also resulted in hundreds of thousands of deaths. He acquired the title "Butcher of Baghdad".
In 2003, a coalition led by the U.S. invaded Iraq to depose Saddam, in which U.S. President George W. Bush and British Prime Minister Tony Blair falsely accused him of possessing weapons of mass destruction and having ties to al-Qaeda. Saddam's Ba'ath party was disbanded and elections were held. Following his capture on 13 December 2003, the trial of Saddam took place under the Iraqi Interim Government. On 5 November 2006, Saddam was convicted by an Iraqi court of crimes against humanity related to the 1982 killing of 148 Iraqi Shi'a, and sentenced to death by hanging. His execution was carried out on 30 December 2006.

I think that the key point here is the "easily reproducible" - because all of them can be scientific questions (even a! it could tell us about about the human psyche!)
but d. is the best answer for a reproducible experiment. B could also make a good experiment, but it would be too expensive to be easily reproducible. C is calling for a more complex analysis that is too complex for an experiment. And a would require more questionnaires than experiments
