Which option is correct. THERE IS ONLY 1 CORRECT option. a,b,c or d!

If a field K is algebraically closed, then every polymomiel with co-
efficients in k has a root in K.
© True. This is an equiral ent way of stating the defiaition of
in algebrically closed field,
True. If K is algebraically closed, then every equation has a
solution in K, So every polynomiel haS a root in K.
False. This only applies to non-consbant poly nomiuls. A nonzero
constant polynomiel such as 1 does 2ot hove a root in K.
False, For example, the polymomiel TT k-w) +1 does not
have a root in K,
