What is the out put of the a <- c(1,"a",TRUE)1    a    TRUE"1"    "a"    "TRUE"'1'    'a'    'TRUE'None of theseClear my choice

The code you provided seems to be written in R language. However, it seems to be incomplete or incorrectly formatted, which makes it difficult to predict the output.

In R, the "<-" symbol is used for assignment. So, "a <- c(1,"a",TRUE)" is creating a vector 'a' with three elements: the number 1, the string "a", and the logical value TRUE.

However, the rest of the code is not clear. If you're trying to print the vector 'a', you can simply use the print() function or type 'a' in the console.

If the code is corrected to:

a <- c(1,"a",TRUE)
print(a)

The output will be:

[1] "1"    "a"    "TRUE"

This is because when different data types (numeric, character, logical) are combined into a vector, R will coerce the elements to the most complex type, in this case, character. So, the number 1 and the logical value TRUE are converted to character strings "1" and "TRUE", respectively.
