As per the condition we are told that all -ve numbers

Let's take \(a < b < c < d < 0\) as \(-100 < -10 < -3 < -1 < 0\)

When we sum two numbers obviously we'll get -ve sum for the above case.

When we multiply two -ve digits we get +ve result.

So Col B > Col A.

Given a < b < c < d < 0 that all the four numbers a, b, c, d are negative

A) a - d will be less than 0 because a is a bigger negative than d and so a - d will always result in a negative

B) bc => this is product of two negative numbers, which will always be positive

Hence quantity B is bigger, Answer choice B
