限定性和非限定性的问题

234. The physical structure of the human eye enables it to sense light of wavelengths up to 0.0005 millimeters; infrared radiation, however, is invisible because its wavelength--0.1 millimeters--is too long to be registered by the eye.

(A)  infrared radiation, however, is invisible because its wavelength--0.1 millimeters--is too long to be registered by the eye

(B)   however, the wavelength of infrared radia­tion--0.1 millimeters--is top long to be registered by the eye making it invisible

(C)  infrared radiation, however, is invisible because its wavelength--0.1 millimeters--is too long for the eye to register it

(D)  however, because the wavelength of infrared radiation is 0.1 millimeters, it is too long for the eye to register and thus invisible

(E)   however, infrared radiation has a wavelength of 0.1 millimeters that is too long for the eye to register, thus making it invisible

Choice E produces an illogical statement by using a restrictive clause introduced by that where a comma followed by the nonrestrictive "which" is required: a wavelength of 0.1 millimeters that is too long nonsensically suggests that not all wavelengths of 0.1 milli­meters are too long for the eye to register.

关于限定性和非限定性 ,that 与which的含义我不清楚,按上面的题举例,哪位能帮解释一下呢,谢谢啊
