How does R do basic mathematical operations on a vector $($or numeric data frame$)?$ That is$,$ if I have a numeric vector called vec and run the code vec$*10,$ how does R execute the multiplication?

Question $3$ Select one:

a$.$

R doesn$$t allow these kinds of operations on vectors.

b$.$

R applies the operation element$-$wise.

c$.$

R applies the operation to only the first element of the vector.

d$.$

R does the arithmetic on the average of the vector and returns that single number.
