Jawaban:

c. will be

I will be a veterinary doctor, because I am interested in animal.

Penjelasan:

Dalam penggunaan modal verb termasuk will (yang lain adalah: can, shall, may, might, could, should, would, ought to) ada 2 cara:

1) Jika dilanjutkan dengan verb, maka strukturnya:

subjek + modal + verb 1 (+ objek/keterangan)

Contoh:

- I will come => subjek + modal (will) + verb1

- She can eat the cake => subjek + modal (can) + verb1 + objek

- You should walk slowly => subjek + modal (should) + verb + keterangan

2) subjek + modal + be  + noun/adjective/adverb

(ini dipakai kalau kalimatnya tidak mengandung kata kerja/verb)

Contoh:

- I will be there tomorrow => subjek + will be + adverb

- Next year I will be a doctor => adverb + subjek + will be + noun

- He will be angry => subjek + will be + adjective
