d. multifactorial inheritance.

Explanation:

Multifactorial inheritance also called "many factors" inheritance are involved in causing a birth defect or aftermath effect after birth. The factors are usually both genetic and environmental, where a combination of genes from both parents, in addition to unknown environmental factors, produce the trait or condition in an offspring.

In the case of the twins who was raised speaking only English, it was due to influence of environmental factors, had it been he/she was introduced to speaking English and french like the other twin raised from the bilingual household, it would have been easier for him/her learning French.
