If the conditional statement “if my dog barks, he will get sent to his kennel,” is true, which statement must also be true A. If my dog get sent to his kennel, he barked
B. If my dog did not get sent to his kennel, he did not bark
C. None must be true
D. If my dog does not bark, he will not get sent to his kennel

Please answer this

D. If my dog does not bark, he will not get sent to his kennel

Explanation:

This is the only answer with the same parallelism used.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
