Red cabbage juice contains a natural pH indicator that changes colors depending on the acidity of the solution. The pigment in red cabbage that causes the red color change is called flavin (an anthocyanin). ... At a lower pH, more hydrogen ions are in solution, and therefore the solution is acidic
Actually I don't know but I tried so I hope it helped u!

I think its the first one
Explanation:
Answer:
A. Strong Acid Strong Base
D. ... 100%
Explanation:
The reaction of hydrobromic acid and sodium cyanide is a strong acid-strong base reaction. In solution, sodium cyanide functions as a strong base and reacts violently with strong acids. For strong acid- strong base reaction, the extent of reaction is usually 100%.
The molecular reaction equation is
NaCN(aq) + HBr(aq) ---------> NaBr(aq) + HCN(aq)
Ionically:
H3O+(aq) + CN- (aq) ----------> HCN(aq) +H2O (l)
HCN(aq) is a weak acid.
