next we check option C

$(7^3)^3=7^(3\cdot3)=7^9$

option C is equivalent to the given expression

next is option D

$7^4+7^5\\e7^9$

option D is not equivalent to the given expression

lastly we check option E

$7^4\cdot7^5=7^((4+5))=7^9$

option E is equivalent to the given expression

from the options given, only option B, C and E are equivalent to the given expression.
