Aperson who is biologically female but identifies with the male gender and has undergone surgery to alter her body is considered

transsexual
a cross-dresser

B, transsexual

Explanation:

A transsexual person does not accept their gender identity and undergoes medical treatment to align with their chosen gender.

Transgender is another term for transsexual but a transgender person does not necessarily seek medical assistance to change their gender identity.

The transition from one sex to another starts with hormone therapy where gender specific traits are stopped or enhanced. Later on, sex reassignment therapies are introduced (surgery), and some psychological help is offered in order to help adjusting to the new gender.  

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
