Test your knowledge in product of vectors,angle between vectors etc

answer to Q4 of products of vectors test in the answer key has been given as 26 instead of 20

In Q4 the ans is 2x0 3x0 5x4=20, in Q7 (-12 2c - 6)= 6 which gives c= 12. Both these values are therein the options. Could you elaborate what mistake you found
