Hello aspirant

Correct option is a) alkaline, salty

Human blood is slightly alkaline between  pH  7.35 to 7.45 and it is salty due to break down of sodium and chloride ions in blood from our food. The salt we consume in our food dissociates into sodium and chloride ions.

Hello dear

The human blood has a pH value in between 7.35-7.45 so it is definitely alkaline in nature .

But it is jot salty in taste . So the best option may be (d) according the my knowledge best

Good luck

Hello Aspirant !
