Which of the following are reasons why declarative expressions are preferred over procedural rules(choose three) ?
a.They perform better, making application response times better.
b.Since they are declarative, PRPC determines when to run them, making applications easier to change.
c.Since they are declarative, PRPC determines when to run them, making errors less likely.
d.Separating the calculation from other logic makes maintenance and delegation easier.
e.They are the only way to execute a decision tree, table or map value.
Correct answer: b,c,d
Generally, we will get better response time by using declare expressions.
So, considering response time we can have first option as one of the answer .But, why we are not choosing that answer ?
