I cannot find the picture, so I gonna proceed by elimination:
1 and 4 are false sentences: blood veins transport deoxygenated blood.
2 and 3 are both correct sentences, so now you need to see where the location of the labeled blood vessel is:

If it is the vessel between the lung and the heart, then it is probably an pulmonary vein.

<span>Headaches, upset stomachs, and hives are classified as acute reaction to stress. Acute means temporary or short term but shouldn't be tolerated in the long-run and must be dealt accordingly in order not to aggravate the situation. Headaches might lead to migraine or upset stomach might lead to intestinal problems so as early as possible this must be treated immediately.</span>
