Answer:
c. Exponentiation has the highest precedence.
Explanation:
Operator precedence decides how an expression is evaluated. For example, Multiplication has higher precedence than addition, therefore a+b*c will be evaluated as a + (b*c). (expression in bold is evaluated first, then added to a)
Option a is wrong since assignment ( = ) has the lowest precedence, therefore addition and subtraction will be evaluated first.
Option b is wrong since exponentiation is right associative.
Option d is wrong because multiplication can never be unary.
Precedence of basic python operators is listed below (Order Highest to lowest):
1) Exponentiation (**)
2) Multiplication (*) , Division (/), Modulus (%). (Same rank means equal precedence)
3) Addition (+), Subtraction(-)
