will go with A

stmnt1 - we have n^2 is not equal to 0

from question stem we have | n+5| = 5 so n = 0 or -10. n is not 0 so n will be -10. hence suff

stmnt2 - n^2 + 10n = 0 => n(n+10) = 0 so n = 0 or -10. both these values satisfy the condition as given in question stem. hence insuff

(1) n^2 is not equal to 0.
(2) n^2 + 10n = 0

|n+5| = 5 => n+5 = 5 and -n-5 = 5
=> n = 0 or n = -10

stmt1: n^2 is not equal to 0 means n <> 0 hence n = -10 so suff

stmt2:n^2+10n = 0 => n = 0 or n = -10 not suff to answer the value of n
Hence A stmt 1 is suff
